-30x+15=3x+6-21
Multiply both sides of the equation by -3.
-30x+15=3x-15
Subtract 21 from 6 to get -15.
-30x+15-3x=-15
Subtract 3x from both sides.
-33x+15=-15
Combine -30x and -3x to get -33x.
-33x=-15-15
Subtract 15 from both sides.
-33x=-30
Subtract 15 from -15 to get -30.
x=\frac{-30}{-33}
Divide both sides by -33.
x=\frac{10}{11}
Reduce the fraction \frac{-30}{-33} to lowest terms by extracting and canceling out -3.
