4\times 18=x\times 6
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 4x, the least common multiple of x,4.
72=x\times 6
Multiply 4 and 18 to get 72.
x\times 6=72
Swap sides so that all variable terms are on the left hand side.
x=\frac{72}{6}
Divide both sides by 6.
x=12
Divide 72 by 6 to get 12.
