15120-28y+15y=9998
Use the distributive property to multiply 28 by 540-y.
15120-13y=9998
Combine -28y and 15y to get -13y.
-13y=9998-15120
Subtract 15120 from both sides.
-13y=-5122
Subtract 15120 from 9998 to get -5122.
y=\frac{-5122}{-13}
Divide both sides by -13.
y=394
Divide -5122 by -13 to get 394.
