8x+20=3\times 40
Multiply both sides by 40.
8x+20=120
Multiply 3 and 40 to get 120.
8x=120-20
Subtract 20 from both sides.
8x=100
Subtract 20 from 120 to get 100.
x=\frac{100}{8}
Divide both sides by 8.
x=\frac{25}{2}
Reduce the fraction \frac{100}{8} to lowest terms by extracting and canceling out 4.
