72x+1200=\left(x+15\right)\times 75
Multiply 15 and 80 to get 1200.
72x+1200=75x+1125
Use the distributive property to multiply x+15 by 75.
72x+1200-75x=1125
Subtract 75x from both sides.
-3x+1200=1125
Combine 72x and -75x to get -3x.
-3x=1125-1200
Subtract 1200 from both sides.
-3x=-75
Subtract 1200 from 1125 to get -75.
x=\frac{-75}{-3}
Divide both sides by -3.
x=25
Divide -75 by -3 to get 25.
