-8x+8=4x+5
Use the distributive property to multiply -8 by x-1.
-8x+8-4x=5
Subtract 4x from both sides.
-12x+8=5
Combine -8x and -4x to get -12x.
-12x=5-8
Subtract 8 from both sides.
-12x=-3
Subtract 8 from 5 to get -3.
x=\frac{-3}{-12}
Divide both sides by -12.
x=\frac{1}{4}
Reduce the fraction \frac{-3}{-12} to lowest terms by extracting and canceling out -3.
