2x-5x+10=-3+5x-27
Use the distributive property to multiply -5 by x-2.
-3x+10=-3+5x-27
Combine 2x and -5x to get -3x.
-3x+10=-30+5x
Subtract 27 from -3 to get -30.
-3x+10-5x=-30
Subtract 5x from both sides.
-8x+10=-30
Combine -3x and -5x to get -8x.
-8x=-30-10
Subtract 10 from both sides.
-8x=-40
Subtract 10 from -30 to get -40.
x=\frac{-40}{-8}
Divide both sides by -8.
x=5
Divide -40 by -8 to get 5.
