\frac{30}{x}=\frac{18}{3}
Divide both sides by 3.
\frac{30}{x}=6
Divide 18 by 3 to get 6.
30=6x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
6x=30
Swap sides so that all variable terms are on the left hand side.
x=\frac{30}{6}
Divide both sides by 6.
x=5
Divide 30 by 6 to get 5.
