4x-2x+4=-9+5x-8
Use the distributive property to multiply -2 by x-2.
2x+4=-9+5x-8
Combine 4x and -2x to get 2x.
2x+4=-17+5x
Subtract 8 from -9 to get -17.
2x+4-5x=-17
Subtract 5x from both sides.
-3x+4=-17
Combine 2x and -5x to get -3x.
-3x=-17-4
Subtract 4 from both sides.
-3x=-21
Subtract 4 from -17 to get -21.
x=\frac{-21}{-3}
Divide both sides by -3.
x=7
Divide -21 by -3 to get 7.
