10n\times 10-3n\times 4=300
Variable n cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 300n, the least common multiple of 30,100,n.
100n-3n\times 4=300
Multiply 10 and 10 to get 100.
100n-12n=300
Multiply 3 and 4 to get 12.
88n=300
Combine 100n and -12n to get 88n.
n=\frac{300}{88}
Divide both sides by 88.
n=\frac{75}{22}
Reduce the fraction \frac{300}{88} to lowest terms by extracting and canceling out 4.
