x\times 12=15\times 15
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 15x, the least common multiple of 15,x.
x\times 12=225
Multiply 15 and 15 to get 225.
x=\frac{225}{12}
Divide both sides by 12.
x=\frac{75}{4}
Reduce the fraction \frac{225}{12} to lowest terms by extracting and canceling out 3.
