math 012 double check me please
posted by amy .
subtract -12 from both sides and that leaves
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
Your first two steps are fine. On the third, in which you go from
12x - 12 = 10x - 43
-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.
