18-15y-6y=4
Use the distributive property to multiply 3 by 6-5y.
18-21y=4
Combine -15y and -6y to get -21y.
-21y=4-18
Subtract 18 from both sides.
-21y=-14
Subtract 18 from 4 to get -14.
y=\frac{-14}{-21}
Divide both sides by -21.
y=\frac{2}{3}
Reduce the fraction \frac{-14}{-21} to lowest terms by extracting and canceling out -7.
