20x-28=0
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 4x.
20x=28
Add 28 to both sides. Anything plus zero gives itself.
x=\frac{28}{20}
Divide both sides by 20.
x=\frac{7}{5}
Reduce the fraction \frac{28}{20} to lowest terms by extracting and canceling out 4.
