3\times 3=13y
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 15y, the least common multiple of 5y,15.
9=13y
Multiply 3 and 3 to get 9.
13y=9
Swap sides so that all variable terms are on the left hand side.
y=\frac{9}{13}
Divide both sides by 13.
