4x-4-4x+8=4x+7-7x
Add -9 and 5 to get -4.
-4+8=4x+7-7x
Combine 4x and -4x to get 0.
4=4x+7-7x
Add -4 and 8 to get 4.
4=-3x+7
Combine 4x and -7x to get -3x.
-3x+7=4
Swap sides so that all variable terms are on the left hand side.
-3x=4-7
Subtract 7 from both sides.
-3x=-3
Subtract 7 from 4 to get -3.
x=\frac{-3}{-3}
Divide both sides by -3.
x=1
Divide -3 by -3 to get 1.
