Answer 1

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
