n\times \frac{1}{2}=5\times 7
Variable n cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 5n, the least common multiple of 5,n.
n\times \frac{1}{2}=35
Multiply 5 and 7 to get 35.
n=35\times 2
Multiply both sides by 2, the reciprocal of \frac{1}{2}.
n=70
Multiply 35 and 2 to get 70.
