20v=7\times 5
Variable v cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 14v, the least common multiple of 7,2v.
20v=35
Multiply 7 and 5 to get 35.
v=\frac{35}{20}
Divide both sides by 20.
v=\frac{7}{4}
Reduce the fraction \frac{35}{20} to lowest terms by extracting and canceling out 5.
