120+15y+6y=-15
Use the distributive property to multiply 5 by 24+3y.
120+21y=-15
Combine 15y and 6y to get 21y.
21y=-15-120
Subtract 120 from both sides.
21y=-135
Subtract 120 from -15 to get -135.
y=\frac{-135}{21}
Divide both sides by 21.
y=-\frac{45}{7}
Reduce the fraction \frac{-135}{21} to lowest terms by extracting and canceling out 3.
