Question

The sum of two rational numbers is -8. if one of the is -8/17, find the other. plz help me ​

Answer 1

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 2

• - 7 9/17

Explanation:

The other number is x:

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