4x-60+3x=5x
Use the distributive property to multiply -3 by 20-x.
7x-60=5x
Combine 4x and 3x to get 7x.
7x-60-5x=0
Subtract 5x from both sides.
2x-60=0
Combine 7x and -5x to get 2x.
2x=60
Add 60 to both sides. Anything plus zero gives itself.
x=\frac{60}{2}
Divide both sides by 2.
x=30
Divide 60 by 2 to get 30.
