1%2F5%2B3%2Fy=-3%2F5 Start with the given equation.


3%2Fy=-3%2F5-1%2F5 Subtract 1%2F5 from both sides.


3%2Fy=%28-3-1%29%2F5 Combine the fractions.


3%2Fy=-4%2F5 Subtract.


3=%28-4%2F5%29%2Ay Multiply both sides by y


3%2A5=-4%2Ay Multiply both sides by 5


15=-4%2Ay Multiply


15%2F-4=y Divide both sides by -4


-15%2F4=y Simplify


So the solution is y=-15%2F4 which in decimal form is y=-3.75


So you have the correct answer.
