18\times 18=x\times 12
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 18x, the least common multiple of x,18.
324=x\times 12
Multiply 18 and 18 to get 324.
x\times 12=324
Swap sides so that all variable terms are on the left hand side.
x=\frac{324}{12}
Divide both sides by 12.
x=27
Divide 324 by 12 to get 27.
