Step-by-step explanation:

1. 3n + 4 = 25

3n = 25 - 4

3n/3 = 21/3

n = 7

2. 3n - 6 = 42

3n = 42 + 6

3n/3 = 48/3

n = 16

3. 2x + 5 = 13

2x = 13 - 5

2x/2 = 8/2

x = 4

4. 3n + 4n - 8 = 11n

7n - 8 = 11n

11n - 7n = -8

4n/4 = -8/4

n = -2

5. 8n - 5 = 3n - 10

8n - 3n = -10 + 5

5n/5 = -5/5

n = -1
