Answer:
![x=48](https://tex.z-dn.net/?f=x%3D48)
Step-by-step explanation:
![\displaystyle{\frac{8(6-x)}{7}={-x}}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%5Cfrac%7B8%286-x%29%7D%7B7%7D%3D%7B-x%7D%7D)
Multiply both sides by 7:
![\displaystyle{8(6-x)=-7x}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B8%286-x%29%3D-7x%7D)
Distribute the left side:
![\displaystyle{48-8x=-7x}](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B48-8x%3D-7x%7D)
Add <em>8x</em> to both sides:
![48=x](https://tex.z-dn.net/?f=48%3Dx)
Rational, because 15 can be made into a fraction. Like 15/1. Hope his helps.
