5xy+3=5xy+y\times 3
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by y.
5xy+3-5xy=y\times 3
Subtract 5xy from both sides.
3=y\times 3
Combine 5xy and -5xy to get 0.
y\times 3=3
Swap sides so that all variable terms are on the left hand side.
y=\frac{3}{3}
Divide both sides by 3.
y=1
Divide 3 by 3 to get 1.
