2x^{2}+4x-4=2x^{2}+5x-3
Combine x^{2} and x^{2} to get 2x^{2}.
2x^{2}+4x-4-2x^{2}=5x-3
Subtract 2x^{2} from both sides.
4x-4=5x-3
Combine 2x^{2} and -2x^{2} to get 0.
4x-4-5x=-3
Subtract 5x from both sides.
-x-4=-3
Combine 4x and -5x to get -x.
-x=-3+4
Add 4 to both sides.
-x=1
Add -3 and 4 to get 1.
x=-1
Multiply both sides by -1.
