20-3x-5x=-10
Subtract 5x from both sides.
20-8x=-10
Combine -3x and -5x to get -8x.
-8x=-10-20
Subtract 20 from both sides.
-8x=-30
Subtract 20 from -10 to get -30.
x=\frac{-30}{-8}
Divide both sides by -8.
x=\frac{15}{4}
Reduce the fraction \frac{-30}{-8} to lowest terms by extracting and canceling out -2.
