84=x\times \frac{44}{2.2}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
84=x\times \frac{440}{22}
Expand \frac{44}{2.2} by multiplying both numerator and the denominator by 10.
84=x\times 20
Divide 440 by 22 to get 20.
x\times 20=84
Swap sides so that all variable terms are on the left hand side.
x=\frac{84}{20}
Divide both sides by 20.
x=\frac{21}{5}
Reduce the fraction \frac{84}{20} to lowest terms by extracting and canceling out 4.
