20-4Q-2Q=0
Subtract 2Q from both sides.
20-6Q=0
Combine -4Q and -2Q to get -6Q.
-6Q=-20
Subtract 20 from both sides. Anything subtracted from zero gives its negation.
Q=\frac{-20}{-6}
Divide both sides by -6.
Q=\frac{10}{3}
Reduce the fraction \frac{-20}{-6} to lowest terms by extracting and canceling out -2.
