in a certain fraction, the denominator is 5 less than the numerator. if 5 is added to both the numerator and the denominator, the resulting fraction is equivalent to 5/4. find the original fraction
...
let x=numerator
x-5 = denominator
..
x+5/(x-5+5)=5/4
x+5/x=5/4
5x=4x+20
x=20
original fraction=20/15
