18\times 6=x\times 9
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.
108=x\times 9
Multiply 18 and 6 to get 108.
x\times 9=108
Swap sides so that all variable terms are on the left hand side.
x=\frac{108}{9}
Divide both sides by 9.
x=12
Divide 108 by 9 to get 12.
