Would it not be 936? Or is it just 9, 36?

[insanity745]

where did the 36 come from?

[drakekale]

@insanity745 4x9 is 36 + another 9 = 45

[HazeHazeGoAway]

He definitely has perfected the art of teaching. These videos helps way more than my current teacher. Plus he's hot! I'd love to earn a little extra credit!



[Agaotaku]

he is awesome!! great teacher...plus cute...

[ALFernandez24]

If youtube ever gets shut down, I think My math grade will drop 40 percent

[TheThoughtGarden]

If the first number is four times the second number, shouldn't the first number be 36 and the second number be 9? I know that it doesn't actually matter for this particular problem, but it's still something to consider.

[tnt1167]

ok ok ok well umm how do i put this but do you have some happy in you or are you cold blooded and feel no pain or joy

If only YouTube was my school.

lol.

[HenryLovesMaths]

This is toooooooo easy!!!

[MrBonification]

where do you get the 5 and the 36 ... you didn't explain it... x is = 1? so 1+4x = 5x ? is that ?

[jacobpjny]

@MrBonification he combined like terms with the 1k and 4x and he times 9 with 4

[asip21]

where do u get the 5? please eplain where u get the 5

[AFullNelson]

@asip21 ......X or whatever is valued at 1 always. This is the "invisible 1" so X=1 P=1 and any unknown letter is valued at 1. But 2X is 2 times X. I suck at math..but I know that X (or whatever stupid letter they use) is 1. so X=1X. I'm flunking math for the sixth time...but that's all I know.

[asip21]

where do u get the 5?

[deynimz]

@asip21 you add x + 4x and thats 5x

[asip21]

@deynimz x=1x?

[deynimz]

@asip21 yes, exactly. they just don't write the 1 b/c its like overstated.

so 1x+4x=5x

and then the equation would be: 5x=45

divide both sides by 5

5x/5=45/5

x=9

Hope this helps :)

[jameslewis8383]

cant hear cause of the gay music

[chocolovemocha]

ohh ma men.. where di yu get the 5 and 36?

[ShineyGreenGlitter]

WTF!! Where did he get 5??

[TheJoeHawkinsShow]

@ShineyGreenGlitter he plused the like terms (x+4x) equals 5 :)

[ShineyGreenGlitter]

@TheJoeHawkinsShow But how does he know what x equals :(

[TheJoeHawkinsShow]

@ShineyGreenGlitter ok. since its ( 5 times x) you have to do an inverse operation and switch the 5 * x to 5%x . and do that to both sides. so five divid by 45 is 9 :) hope u understand

[ShineyGreenGlitter]

@TheJoeHawkinsShow Ohhhhhhhh.....................­(continues for 40 seconds) Thanks. ;)

[betobroxz5123]

how do you get 36

[johnfranklinwilliam]

@betobroxz5123 4(x)=36 and since x = 9. its 4(9)=36

[ThatRandomGuy2143]

Oh yeah I did this in 5th grade.

[lalanto341]

this teacher was amazing!!!!

He teach us for FREEEEEEE!!

[htownking85]

How did he get 5x?

[lolgearup]

@htownking85 x + 4x =5x

[emoprincez01]

@htownking85 x + 4x= 5x (x's constant is 1, so add 1 and 4 and just copy the x. )

[luvbeingmama83]

ok where did the 5x come from??

[lolgearup]

@luvbeingmama83 x + 4x = 5x

[666jong]

thnx to you i almost perfected my exam thnx again :D

[Firstpiro]

wow this is better than my college professor xd just this is a smaaller problem but it helped me take what looked like a mile and break it down into a simplified way of solving the problem

[54321blastoffkayferg]

ok first of alll X is not a number and 2nd WHY THE CRAP DO I NEED TA KNOW THIS ANYWAY?!?!?!?!?!?

[27chantal101]

@54321blastoffkayferg firstly why the heck did you see this video? secondly make the X in the sentence Ok first of all X is not a number = it should be small x thirdly you should not be still in the grade on where you should learn algebra.

[54321blastoffkayferg]

@27chantal101 ummm how r u gonna tell me what grade im in????

[Casna101]

@54321blastoffkayferg

Of course x isn't a number, it is an unknown. It stands for an unknown number. A simple example of how a variable works would be:

4 + x = 8

In this situation you need to know what x is. You would solve this by subtracting the 4 over to the opposite side, or in other words, subtract it from the 8. x = 8 - 4

x = 4

Thus, 4 + 4 = 8

It gets much more complex though, and is used to find things such as amounts needed for mixtures, amounts of money, lengths, widths, etc.

[sliccflip]

only if you were my teacher, i would never have dropped out of high school

[cortes1988]

They need to make more word problem videos!

[cortes1988]

word problems are the worst!

[ForeverSn1per]

I dont get how he got 5x?

[Jboi11118]

@ForeverSn1per add the x to 4x , hence x + 4x = 5x you can add the variables just like u can multiply and divide them

[VeryCuteBoiBoi]

i dun understand the 3rd steps

[ubathegreat]

THANK YOU SO MUCH!!! I STILL LOATH MATH BUT THIS MIGHT HELP ME LIKE IT A LITTLE MORE. =D

[Skaterrify]

Keep Pressing "2". You have to press it REALLY fast.

[captainofpineapples]

yes it was clear.....but if my math teacher was like this..........ZZZZZZZZZZZZZZZZ­ZZZZ huh what TEST ........ shit...........

[cnuts83]

if its two different numbers why wouldn't there be two different variables?

[SiobhanMaya]

I learn waaaaay more on youtube than in class

[Champsr0ck2347]

@SiobhanMaya yeah,youtube should be our school ya kno

[thegame52291]

this guys literally better than anyone else on youtube...good shit sir!

[damiaweave]

i got the answer in 4 seconds lol

[FranzAntonMesmer]

Well done.

[evanjo1000]

why?

[07sepehr]

i dont get it

[shaider61921]

1 problem how to get the Y?

[louisep613]

One number is 800 less than three times the other, and their sum is 1200. find the numbers. help?? answer pls. :(

[damncritics]

@louisep613 That's a simple question turned seemingly complicated because of the way its phrased. first number > x second number > y x + 800 = 3y x + y = 1200 3x + 3y = 3600 3x + x + 800 = 3600 4x = 2800 x = 700 (first number) 700 + y = 1200 y = 500 (second number) Any questions?

[ThePuRpLeHD]

@damncritics uhhhhhhhh...............

[KBerryful]

I just realized that the math teachers are not doing their jobs AT ALL, this is sad that I can learn,more on youtube than in actual class.

[gracefullbravo]

This made so much sense! These problems always intimidated me on tests. Thank you :D

[sidoghosh]

x+4x=45...5x=45..x=9..huahahah­ah

[ryosakazu]

Thank you So Much It Help A Lot to me!

[superproprocombo]

excellent explanation....this is a big help!

[ralphivan23]

this guy is better than my math teacher.

[Gamerzwillrule1]

dude it's awesome how you seem so calm

[bradlyw420]

so, what gets me is how do you simplify the (4x) into (5x)? 

[nathalia1998emo]

simply good.. :)

[tom9993thejock]

im only in 5th grade i need to know how to do my word probs but idk y but i think i got this the x is a symbol of times and the numbers broke apart are the steps that helped me tho the + is a symbol of adding the steps to see what u get when u do the other steps together idk i dont think i am correct im not this advanced tho...

[444zane3]

@tom9993thejock think of X as any number. we call this a variable. in equations, to show the multiplication of two numbers we put a dot in between those numbers at mid-height. you should watch equation solving videos or you should wait 1 or 2 yrs.

[aeiou2304]

thnx dude

[MIKEDHINO]

thank uu master!!

[useurcamera]

its summer in our place so i watch these videos so i wont forget my math =)

[SheWhoWrites07]

he multiplied 9 to 4 to get the value of 4x :o

[LSouljette]

i don get how you got 36.. is it because you multiplied 9x4

or did you bring it out of nowhere?

[herbaljunky]

I started out with 4x/x=4. And 4x-1/2x=4/5 but it did not work out. Someone plz help a brotha out. Thanx

[herbaljunky]

@herbaljunky i got it thanx!

[herbaljunky]

No lie. I fell asleep thinking about this problem and woke up still confused. " The diff in the numerator and the denominator of an improper fraction is 4. If the num is decreases by 1 and the denom doubled, what is the original fraction.

[Danerd9]

thnks!!

[magenguy]

arent you supposed to do a let statement first?

[nitro300]

i use some of these examples on the asvab

[rfaris253]

Easy, 9 and 36

[thevideoman9]

senence.. its sentence!, different accent lol.

[vega240sx]

senence by senence.  LOL great explanation by the way.

[skullzz1991]

i always though there was only one answer like x=9 but theres more?

[Lookoutediting]

Thanks

[DBZxGohan]

im suck in word problem n im going for the act this year

[Farrahmack]

I'm having the same prob...

[almondtealeaf2]

[carlos2709]

i learned how to do that when i was 4 yrs

[ShyanneRhea8]

if thats so, then why are you looking at this video now? .... ://

[monimstarfox]

this guy is so good at explaining! so clear and precise!

[ZedXIV]

@JasonJRY unlike my teacher

[NummySooshi]

that was so easy....how could I not do that? Thank you very much

[mathproblems]

you ahould have told the students how to check your answer to see if it correct. good explanation

[ChipmunkNation22]

awesome thanks i stink at word problems you guys rock
