100\times 72=801x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 100x, the least common multiple of x,100.
7200=801x
Multiply 100 and 72 to get 7200.
801x=7200
Swap sides so that all variable terms are on the left hand side.
x=\frac{7200}{801}
Divide both sides by 801.
x=\frac{800}{89}
Reduce the fraction \frac{7200}{801} to lowest terms by extracting and canceling out 9.
