20\times 12=x\times 5
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 x,20.
240=x\times 5
Multiply 20 and 12 to get 240.
x\times 5=240
Swap sides so that all variable terms are on the left hand side.
x=\frac{240}{5}
Divide both sides by 5.
x=48
Divide 240 by 5 to get 48.
