8\times 5=x\times 20
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 8x, the least common multiple of x,8.
40=x\times 20
Multiply 8 and 5 to get 40.
x\times 20=40
Swap sides so that all variable terms are on the left hand side.
x=\frac{40}{20}
Divide both sides by 20.
x=2
Divide 40 by 20 to get 2.
