Answer:
see below
Step-by-step explanation:
5) 4n + 6 - 2n = (2n + 3)
No solution
6) 6m - 8 = 2 + 9m - 1
- 6m - 9m = 2 - 1 + 8
- -3m = 9
- m = 9/-3
m = -3
7) -v + 5 + 6v = 1 + 5v + 3
- -v + 6v - 5v = 1 + 3 - 5
- 0 = -1
No solution
8) 2(3b - 4) = 8b - 11
- 6b - 8 = 8b - 11
- 6b - 8b = 8 - 11
- -2b = -3
b = 3 / 2
