5\times 3-7\times 2=35y
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 35y, the least common multiple of 7y,5y.
15-14=35y
Do the multiplications.
1=35y
Subtract 14 from 15 to get 1.
35y=1
Swap sides so that all variable terms are on the left hand side.
y=\frac{1}{35}
Divide both sides by 35.
