Question

Answer 1

Let other one be x

ATQ

$\\ \sf\longmapsto x+\dfrac{-8}{17}=-8$

$\\ \sf\longmapsto\dfrac{17x-8}{17}=-8$

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

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

$\\ \sf\longmapsto 17x=-128$

$\\ \sf\longmapsto x=\dfrac{-128}{17}$

Answer 2

Answer:

• - 7 9/17

Step-by-step explanation:

The other number is x:

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