x\times \frac{84}{8.4}=120
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
x\times \frac{840}{84}=120
Expand \frac{84}{8.4} by multiplying both numerator and the denominator by 10.
x\times 10=120
Divide 840 by 84 to get 10.
x=\frac{120}{10}
Divide both sides by 10.
x=12
Divide 120 by 10 to get 12.
