Algebra: Solving a System of Equations

[AssiaHamidiB]

I have been watching about 7 videos of math teachers, all of them explaining solving systems of equations. You are the only teacher that made me understand it! Thank you so much.



[soppiedekuthond]

i once had this at school, but never understand it. Or didn't i pay any attention to it?

well at least... i do now and i think i understand it right now.

thanks to you

I've met Pat McKeague (the man on camera) at several conferences. He's a very nice man and willing to share his ideas with everyone. His website is free -- much cheaper than what the textbook publishers charge.

nice grade 6 math work im sure retards strugle with this

[Johnsondmms]

@comment69873 At least us retards can spell.

[Krazyness]

what if the equation is

x=2y+9

x+5y+5=0

[InfernoXtreme1]

old guy is cool!

[kurticusandfrexual21]

THIS IS GODLY, I REALLY LOVE THIS TEACHER.

[NightShadeslayer]

Hi :)

What about one with exponents?

and variables in the exponents?

With different prime bases?

[MDubBeezy]

This was extremely helpful. Painful hours of struggle relieved by 3 minutes, 18 seconds of mathematical insight. Thanks!

[SUPERspark64ify]

OOLLLLLDDD MOTHERFUCKER!!!! lol....but his method works.

[Msbbopalula]

Very well explained. I understood it the first time and did not have to watch it over and over.THANK YOU!!!

[MysTeri0usMatT7]

good elimination method lesson, does he have a graphing systems of equations lesson?

[psd90x]

You're a very good teacher. Thanks for the video

[msgwaiting]

my math teacher can do math but cant teach math

[teamhuggy]

He got the 3 from the Y so he can take it out

[megankittty]

vvv agreed. wtf.

[mixolidianmode]

where the hell he got the -3 from?

[videomaster54]

Very Very helpful thanks!

[sushrika0just0live]

thanks soo much!

i finally understand!!

[NCSportsMan70]

My algebra 1 teacher just copies everything out of a math book and she doesn't even know how to do it.

[enrichedd]

@NCSportsMan70

shitty teachers are better than no teachers :/

[NCSportsMan70]

@enrichedd Most of the time

[InfernoXtreme1]

@enrichedd what do u have against old men!

[InfernoXtreme1]

@enrichedd what do u have against old men!?

[Jon58840]

Oh man, thanks so much, I have to solve a system of equations for my Math 10H homework for IB even though we were never taught this.

[Hawkeyeharley]

I wish my teacher was this good. Mine enjoys sounding smart and belittles us when we make a mistake.

[KingTyger]

yea, i have the same problem with mine, but i just make his life a living hell with out of the universe questions an solutions that take forever hahahhaha, ^^ if he was so kind as this teacher here, i be nice, good job in refreshing my memory... wooo back to study...

[purplecurtisimo]

mine is the same way...

[SUPERspark64ify]

@Hawkeyeharley really? Your teacher sounds like a massive DEUCHE......Im sorry, I used to have a math teacher that would teach us for like 15 mins, then leave, and go get stoned or something, she was kinda a bitch too.....but she liked me, cuz im quiet and sweet....ha.

[ricksta1997]

@Hawkeyeharley Absolutely the same i would love to haev a teacher like that cause unlike my teacher i can understand him

[ricksta1997]

@ricksta1997 *have

[tenshikuh]

WOW!! he's great!! its very helpful.. 5 rating!

[525manuel]

hey someone help me look i understand this but this girl thats really smart next 2 me told me that she got 2 lines out of doing this..how does that happen?

[Ploskey]

i need to tell my friends about this. i missed class and had no idea how to use the addition method. thank you so much.

[minhmeo1209]

He worse than my algebra 1 teacher at school

[TENspeaks]

Totally stumped! Not sure where he got the -3 to multiply by the second equation.

[TENspeaks]

Had to watch this many times until I finally understood it.

[awesomeazn95]

@TENspeaks i think cause the top is 3 y, so you times it by 3 so it can be cancle out.

[Ozarkeree]

@TENspeaks He's multiplying the whole second equation by the inverse of the first equation's coefficient of y. That way, both ys will cancel out and only the x variable will be left when the equations are added together. Hope that helps!

[xWindfangx]

thanks this is so much better than yourteachermathhelp

[3plus3is7]

I know this comment is identical to all the other comments posted, but thanks SO MUCH. I was in algebra 1 in 7th grade and in geometry in 8th grade. I'm going into ninth grade, and I got this algebra 2 math packet for the summer with stuff I haven't done in two years. I had completely fogotten EVERYTHING on it, thus I began my search for a decent tutorial. This was SO HELPFUL, now I won't fail the first thing I turn in. :D

[MyNoteToSelf]

I love this MathTV man, thank you so much! I've been in Algebra 1 for almost 3 years now and your videos are the only things that've helped me, haha!

[captainchris12]

O my gosh your a life saver :D

[imdatshyt]

WOW Thank you very much your video was really very helpful. Well done!!!

[THEGREENBEAN52]

dude what school do u teach at

[guitarbandx]

So useful exept my variable always comes out to 7x or so

[LamborghiniChynaDoll]

your amazing i wish you taught at my school, i mean in three minutes you did what takes my professor 50 mins!! thanks so much

[Dart11111]

such a great teacher

[evolucion311]

These videos are great, thank you so much!

[CoasterChick22]

thank you for helping me with this, much easier.

[halliday2010]

thanks i was a little confused there

[1985rocco]

Can you do a video on Synthetic Divition?

[turbold1]

thanks keep it up.. instead of saying same line say that the system has infinitely many solutions

[polarbear60]

Not the same line, but on top of each other would be a better statement in my opinion. Thank you!

[tomthecool]

Why not just multiply the second equation by 2 then subtract it from the first? You overcomplicated it quite a bit...
