20x+40+20x=20
Add 20x to both sides.
40x+40=20
Combine 20x and 20x to get 40x.
40x=20-40
Subtract 40 from both sides.
40x=-20
Subtract 40 from 20 to get -20.
x=\frac{-20}{40}
Divide both sides by 40.
x=-\frac{1}{2}
Reduce the fraction \frac{-20}{40} to lowest terms by extracting and canceling out 20.
