20x\times \frac{1}{20}+x\times 4=20
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+x\times 4=20
Cancel out 20 and 20.
5x=20
Combine x and x\times 4 to get 5x.
x=\frac{20}{5}
Divide both sides by 5.
x=4
Divide 20 by 5 to get 4.
