Let other one be x

ATQ


\\ \sf\longmapsto x+(-8)/(17)=-8


\\ \sf\longmapsto(17x-8)/(17)=-8


\\ \sf\longmapsto 17x-8=17(-8)=-136


\\ \sf\longmapsto 17x=-136+8


\\ \sf\longmapsto 17x=-128


\\ \sf\longmapsto x=(-128)/(17)

Answer:

  • - 7 9/17

Explanation:

The other number is x:

  • -8/17 + x = -8
  • x = -8 + 8/17
  • x = - 7 9/17
