Answer:

see below

Step-by-step explanation:

5) 4n + 6 - 2n = (2n + 3)

  • 2n + 6 = 2n + 3
  • 0 = -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
