9x+3x-12=10x-50+7

12x-12=10x-43

subtract -12 from both sides and that leaves

-12=-2x-43

add 43 to both sides and that leaves 31=2x

then the answer is x=31/2 (a fraction)

im so confused and its even harder trying to type it out and not confuse anyone reading it. lol

- math 012 double check me please -
**Noether**, Sunday, February 1, 2009 at 7:38pmYour first two steps are fine. On the third, in which you go from

12x - 12 = 10x - 43

to

-12 = -2x - 43

I think you mean to say you're subtracting 12x from each side.

Adding 43 to each side leaves 31 = -2x.

Divide each side by -2 to get x = (-31)/2.

So, it looks like you were right, except for dropping a - when subtracting 43.
