18\times 9=x\times 27
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.
162=x\times 27
Multiply 18 and 9 to get 162.
x\times 27=162
Swap sides so that all variable terms are on the left hand side.
x=\frac{162}{27}
Divide both sides by 27.
x=6
Divide 162 by 27 to get 6.
