Answer:

#1

  • 12x + 5 = 1/2(83 + 95)
  • 12x + 5 = 89
  • 12x = 84
  • x = 7

#2

  • 9x + 7 = 1/2(198 + 7x - 8)
  • 18x + 14 = 198 + 7x - 8
  • 11x = 176
  • x = 16

#3

  • 15x - 8 = 1/2(16x + 1 + 5x + 19)
  • 30x - 16 = 21x + 20
  • 9x = 36
  • x = 4

#4

  • 20x - 4 = 360 - 2*72
  • 20x =  220
  • x = 11

#5

  • 13x - 1 = 2(6x + 11)
  • 13x - 1 = 12x + 22
  • x = 23

#6

  • 46 = 1/2(21x - 5 - x - 23)
  • 20x - 28 = 92
  • 20x = 120
  • x = 6

#7

  • 6x - 21 = 1/2(13x - 3 - 3x - 11)
  • 12x - 42 = 10x - 14
  • 2x = 28
  • x = 14

#8

  • 2x + 1 = 1/2(9x - 14 - 4x + 7)
  • 4x + 2 = 5x - 7
  • x = 9

#9

  • 9x - 4 = 180 - 76
  • 9x - 4 = 104
  • 9x = 108
  • x = 12
