(4x +5)/5x + 5 = 13/16
64x + 80 = 65x + 65
X = 80-65 = 15
no. is 4x = 4 × 15 = 60
5x = 5 × 15 = 75
64x + 80 = 65x + 65
X = 80-65 = 15
no. is 4x = 4 × 15 = 60
5x = 5 × 15 = 75

let the fraction be 4x/5x and 5 is added to both
4x+5/5x+5=13/16
64x+65=80x+80
-15=16x
x=-15/16
(4*-15/16)/(5*-15/16)
(-15/4)/(-75/16)
-15*16/4*-75
4/5
4x+5/5x+5=13/16
64x+65=80x+80
-15=16x
x=-15/16
(4*-15/16)/(5*-15/16)
(-15/4)/(-75/16)
-15*16/4*-75
4/5
