7\times 4=5y
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 7y, the least common multiple of y,7.
28=5y
Multiply 7 and 4 to get 28.
5y=28
Swap sides so that all variable terms are on the left hand side.
y=\frac{28}{5}
Divide both sides by 5.
