20=4080x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
4080x=20
Swap sides so that all variable terms are on the left hand side.
x=\frac{20}{4080}
Divide both sides by 4080.
x=\frac{1}{204}
Reduce the fraction \frac{20}{4080} to lowest terms by extracting and canceling out 20.
