x\times 84=84\times 120
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 84x, the least common multiple of 84,x.
x\times 84=10080
Multiply 84 and 120 to get 10080.
x=\frac{10080}{84}
Divide both sides by 84.
x=120
Divide 10080 by 84 to get 120.
