\left(x+4\right)\left(20-2\right)=48
Divide 40 by 2 to get 20.
\left(x+4\right)\times 18=48
Subtract 2 from 20 to get 18.
18x+72=48
Use the distributive property to multiply x+4 by 18.
18x=48-72
Subtract 72 from both sides.
18x=-24
Subtract 72 from 48 to get -24.
x=\frac{-24}{18}
Divide both sides by 18.
x=-\frac{4}{3}
Reduce the fraction \frac{-24}{18} to lowest terms by extracting and canceling out 6.
