Answer:
Option D - Division property of equality
Step-by-step explanation:
Given : Step 8 - ![\frac{-3x}{-3}=-\frac{7}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-3x%7D%7B-3%7D%3D-%5Cfrac%7B7%7D%7B3%7D)
To find : Indicate which property is illustrated in step 8 ?
Solution :
Step 8 - ![\frac{-3x}{-3}=-\frac{7}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-3x%7D%7B-3%7D%3D-%5Cfrac%7B7%7D%7B3%7D)
In step 8 we have seen that -3 is divided both side,
So, The division property of equality is applied to get the result.
![\frac{-3x}{-3}=-\frac{7}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B-3x%7D%7B-3%7D%3D-%5Cfrac%7B7%7D%7B3%7D)
![x=-7](https://tex.z-dn.net/?f=x%3D-7)
Therefore, Option D is correct.
