The answers are 2. B, 3. D, 4. C, and 5. A.
Step-by-step explanation:
Step 1:
For question 2. ![4+4n = -12.](https://tex.z-dn.net/?f=4%2B4n%20%3D%20-12.)
We subtract both sides by 4 to get
![4+4n-4 = -12-4, 4n = -16, n = -4](https://tex.z-dn.net/?f=4%2B4n-4%20%3D%20-12-4%2C%204n%20%3D%20-16%2C%20n%20%3D%20-4)
For question 3.
.
We divide the entire equation by 4 to get
![\frac{4n}{4} = \frac{-12}{4} , n = -3.](https://tex.z-dn.net/?f=%5Cfrac%7B4n%7D%7B4%7D%20%3D%20%5Cfrac%7B-12%7D%7B4%7D%20%2C%20n%20%3D%20-3.)
Step 2:
For question 4. ![\frac{n}{4} = -12.](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B4%7D%20%3D%20-12.)
We multiply both sides by 4 to get
![\frac{n}{4} (4)= -12(4).](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B4%7D%20%284%29%3D%20-12%284%29.)
![n = -48.](https://tex.z-dn.net/?f=n%20%3D%20-48.)
For question 5. ![\frac{n}{4} -4 = -12.](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B4%7D%20-4%20%3D%20-12.)
We add 4 to both sides to get
![\frac{n}{4} -4 +4= -12+4, \frac{n}{4} = -8.](https://tex.z-dn.net/?f=%5Cfrac%7Bn%7D%7B4%7D%20-4%20%2B4%3D%20-12%2B4%2C%20%5Cfrac%7Bn%7D%7B4%7D%20%3D%20-8.)
![n = -32.](https://tex.z-dn.net/?f=n%20%3D%20-32.)
So the answers are 2. B, 3. D, 4. C, and 5. A.
