54\times 112=x\times 72
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 54x, the least common multiple of x,54.
6048=x\times 72
Multiply 54 and 112 to get 6048.
x\times 72=6048
Swap sides so that all variable terms are on the left hand side.
x=\frac{6048}{72}
Divide both sides by 72.
x=84
Divide 6048 by 72 to get 84.
