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