Step-by-step explanation:

let numerator=x

denominator=y

x+1/y=1/5

5(x+1)=y

5x+5=y

5x-y=-5 -----eq. 1

x/y-1=1/7

7x=y-1

7x-y=-1 --------eq. 2

subtracting eq. 2 from eq. 1

5x-y=-5

7x-y=-1

- + +

_____________

-2x=-4

-x=-2

x=2

substituting in eq. 1

5x-y=-5

5×2-y=-5

10-y=-5

-y=-15

y=15

HOPE IT HELPS YOU☺️☺️
