x\times 20=2\times 12,5
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2x, the least common multiple of 2;x.
x\times 20=25
Multiply 2 and 12,5 to get 25.
x=\frac{25}{20}
Divide both sides by 20.
x=\frac{5}{4}
Reduce the fraction \frac{25}{20} to lowest terms by extracting and canceling out 5.
