um im having trouble with fractions just finding the varieble please help

[mbrandl11]

@idfcb

Can you give a specific problem that you're having trouble with? I'll see what I can do from there! :-)

In the first question, if you take away two from both sides of the equation, instead of three, the answer you get is +4 instead of -4

IF YOU EXPLAIN THIS TO ME, I PROMISE I'LL SUBSCRIBE!!!

[mbrandl11]

@DamionCrane We have to remember our overall goal - get the variable by itself. So taking away two doesn't help us since it's not on the same side as the variable. Here's what we'd get, if we start by taking away 2: (1/4)x + 3 - 2 = 2 - 2 (1/4)x + 1 = 0 Then we'd have to subtract one from both sides to get: (1/4)x + 1 - 1 = 0 - 1 (1/4)x = -1 Finally, multiply by 4/1, or just 4 on both sides to get the x by itself and get our answer. 4(1/4)x = -1(4) x = -4 I hope that helps! :-)

you should have done more problems with fractions, that would really help thx

@BeCavtotheMax

I'll add that to my "to do" list!

Thanks dude!! MY TEACHER SUCKS :P

[koldblooded1]

im a really visual learner, its a little hard seeing it sloppy(not a diss im sloppy too) but it is harder to store in my memory for some reason... i like little boxes n steps to fallow... maybe even some diff colors? just some suggestions but thank ya!

[sideshowdan]

Thank you VERY MUCH!! VERY WELL DONE :) REALLY REALLY HELPFUL

@sigilofbolias

Please don't use that language here. Can you be more specific would what is giving you trouble? I'd be happy to help!  :-)

I'm in advanced math

[freckledkid1]

Thanks this is awesomee but do more like one and two I'm only in seventh grade
