Step-by-step explanation:
![6(5 - 8v) + 12 = -54\\30 - 48v + 12 = -54\\- 48v = - 54 - 30 - 12\\-48v = -96](https://tex.z-dn.net/?f=6%285%20-%208v%29%20%2B%2012%20%3D%20-54%5C%5C30%20-%2048v%20%2B%2012%20%3D%20-54%5C%5C-%2048v%20%3D%20-%2054%20-%2030%20-%2012%5C%5C-48v%20%3D%20-96)
![v = \frac{-96}{-48} = 2](https://tex.z-dn.net/?f=v%20%3D%20%5Cfrac%7B-96%7D%7B-48%7D%20%3D%202)
