20-5x+2x-9=2x-14
Add 7 and 13 to get 20.
20-3x-9=2x-14
Combine -5x and 2x to get -3x.
11-3x=2x-14
Subtract 9 from 20 to get 11.
11-3x-2x=-14
Subtract 2x from both sides.
11-5x=-14
Combine -3x and -2x to get -5x.
-5x=-14-11
Subtract 11 from both sides.
-5x=-25
Subtract 11 from -14 to get -25.
x=\frac{-25}{-5}
Divide both sides by -5.
x=5
Divide -25 by -5 to get 5.
