5\times 4=-14y
Variable y cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 5y, the least common multiple of y,5.
20=-14y
Multiply 5 and 4 to get 20.
-14y=20
Swap sides so that all variable terms are on the left hand side.
y=\frac{20}{-14}
Divide both sides by -14.
y=-\frac{10}{7}
Reduce the fraction \frac{20}{-14} to lowest terms by extracting and canceling out 2.
