-3y-8%28-9y-9%29=4%2B3%284-y%29 Start with the given equation.


-3y%2B72y%2B72=4%2B12-3y Distribute.


69y%2B72=4%2B12-3y Combine like terms on the left side.


69y%2B72=-3y%2B16 Combine like terms on the right side.


69y=-3y%2B16-72 Subtract 72 from both sides.


69y%2B3y=16-72 Add 3y to both sides.


72y=16-72 Combine like terms on the left side.


72y=-56 Combine like terms on the right side.


y=%28-56%29%2F%2872%29 Divide both sides by 72 to isolate y.


y=-7%2F9 Reduce.
