18=9y-3y-18
Use the distributive property to multiply -3 by y+6.
18=6y-18
Combine 9y and -3y to get 6y.
6y-18=18
Swap sides so that all variable terms are on the left hand side.
6y=18+18
Add 18 to both sides.
6y=36
Add 18 and 18 to get 36.
y=\frac{36}{6}
Divide both sides by 6.
y=6
Divide 36 by 6 to get 6.
