12\times 2=x\times 80
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 12x, the least common multiple of x,12.
24=x\times 80
Multiply 12 and 2 to get 24.
x\times 80=24
Swap sides so that all variable terms are on the left hand side.
x=\frac{24}{80}
Divide both sides by 80.
x=\frac{3}{10}
Reduce the fraction \frac{24}{80} to lowest terms by extracting and canceling out 8.
