Question

the sum of the numerator and denominator of a fraction is 8 if 3 is added to both of the numerator and denominator of the fraction becomes 3 upon 4 FanFiction

Answer 1

let the numerator be x
let the denominator be y
A. T. Q
x + y = 8
and if
3 is added to numerator then = x+3
3 is added to denominator then = y+3
so,
x+3
$\frac{x + 3}{ y + 3} = \frac{3}{4}$
by cross multiplication
4x + 12 = 3y + 9
4x - 3y = -3
x + y = 8
