Homework Help: math 012 double check me please

Posted by amy on Sunday, February 1, 2009 at 5:50pm.

9x+3(x-4)=10(x-5)+7

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
