60\times 9=x\times 30
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 60x, the least common multiple of x,60.
540=x\times 30
Multiply 60 and 9 to get 540.
x\times 30=540
Swap sides so that all variable terms are on the left hand side.
x=\frac{540}{30}
Divide both sides by 30.
x=18
Divide 540 by 30 to get 18.
