3n=30+n
Variable n cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 30n, the least common multiple of 10,n,-30.
3n-n=30
Subtract n from both sides.
2n=30
Combine 3n and -n to get 2n.
n=\frac{30}{2}
Divide both sides by 2.
n=15
Divide 30 by 2 to get 15.
