![\to x + \frac{5}{7} = \frac{31}{7}\\\\](https://tex.z-dn.net/?f=%5Cto%20x%20%2B%20%5Cfrac%7B5%7D%7B7%7D%20%3D%20%5Cfrac%7B31%7D%7B7%7D%5C%5C%5C%5C)
Subtracting the
from both sides of the equations:
![\to x +\frac{5}{7} - \frac{5}{7} = \frac{31}{7} - \frac{5}{7} \\\\](https://tex.z-dn.net/?f=%5Cto%20x%20%2B%5Cfrac%7B5%7D%7B7%7D%20%20-%20%5Cfrac%7B5%7D%7B7%7D%20%20%3D%20%5Cfrac%7B31%7D%7B7%7D%20%20-%20%5Cfrac%7B5%7D%7B7%7D%20%5C%5C%5C%5C)
![= \frac{31-5}{7} \\\\= \frac{26}{7} \\\\](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B31-5%7D%7B7%7D%20%5C%5C%5C%5C%3D%20%5Cfrac%7B26%7D%7B7%7D%20%5C%5C%5C%5C)

Hello there!
Answer: ⇒ C. -30
_________________________________________________________
Step-by-step explanation:
First you had to remove parenthesis.
![-7*4-|-6|+|4|](https://tex.z-dn.net/?f=-7%2A4-%7C-6%7C%2B%7C4%7C)
Then you multiply by the number.
![=-28-|-6|+|4|](https://tex.z-dn.net/?f=%3D-28-%7C-6%7C%2B%7C4%7C)
Apply absolute value.
![|-6|=6](https://tex.z-dn.net/?f=%7C-6%7C%3D6)
![=-28-6+|4|](https://tex.z-dn.net/?f=%3D-28-6%2B%7C4%7C)
Again apply absolute value.
![|4|=4](https://tex.z-dn.net/?f=%7C4%7C%3D4)
![=-28-6+4](https://tex.z-dn.net/?f=%3D-28-6%2B4)
Simplify it's should be the correct answer.
![=-30](https://tex.z-dn.net/?f=%3D-30)
