9x+3(x4)=10(x5)+7
9x+3x12=10x50+7
12x12=10x43
subtract 12 from both sides and that leaves
12=2x43
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 7:38pm
Your 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.
