Answer:

  • 11. a) 9
  • 12. c) 0
  • 13. c) -1/2
  • 14. d) -3

Step-by-step explanation:

11.

  • -3(x - 11) = 6
  • x - 11 = -2
  • x = 11 - 2
  • x = 9

12.

  • -7x/9 + 2 = 2
  • -7x/9 = 0
  • x = 0

13.

  • -8x + 2 = 6
  • -8x = 4
  • x = 4/(-8)
  • x = -1/2

14.

  • 4x - 5 = -17
  • 4x = 5 - 17
  • 4x = -12
  • x = -12/4
  • x = -3
