3y%2B15=-7%28y%2B5%29 Start with the given equation.


3y%2B15=-7y-35 Distribute.


3y=-7y-35-15 Subtract 15 from both sides.


3y%2B7y=-35-15 Add 7y to both sides.


10y=-35-15 Combine like terms on the left side.


10y=-50 Combine like terms on the right side.


y=%28-50%29%2F%2810%29 Divide both sides by 10 to isolate y.


y=-5 Reduce.
