x\times 12=20\times 13
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 20x, the least common multiple of 20,x.
x\times 12=260
Multiply 20 and 13 to get 260.
x=\frac{260}{12}
Divide both sides by 12.
x=\frac{65}{3}
Reduce the fraction \frac{260}{12} to lowest terms by extracting and canceling out 4.
