5\left(81+9y\right)-75y=-75
Multiply both sides of the equation by 25.
405+45y-75y=-75
Use the distributive property to multiply 5 by 81+9y.
405-30y=-75
Combine 45y and -75y to get -30y.
-30y=-75-405
Subtract 405 from both sides.
-30y=-480
Subtract 405 from -75 to get -480.
y=\frac{-480}{-30}
Divide both sides by -30.
y=16
Divide -480 by -30 to get 16.
