y=3y%2F%28y%2B5%29 Start with the given equation.


y%28y%2B5%29=3y Multiply both sides by y%2B5


y%5E2%2B5y=3y Distribute


y%5E2%2B5y-3y=0 Subtract 3y from both sides.


y%5E2%2B2y=0 Combine like terms.


y%28y%2B2%29=0 Factor out the GCF 'y'


y=0 or y%2B2=0 Use the zero product property


y=0 or y=-2 Solve for 'y' in each case.


So the solutions are y=0 or y=-2
