Answer 1

Explanation:

• Exterior angle is same as sum of remote interior angles.
• Solving for x in each case below.

#7

• 5x + 10 + 58 = 11x + 2
• 5x + 68 = 11x + 2
• 11x - 5x = 68 - 2
• 6x = 66
• x = 11

#8

• 10x - 10 + 30 = 12x - 4
• 10x + 20 = 12x - 4
• 12x - 10x = 20 + 4
• 2x = 24
• x = 12

#9

• 46 - 1 + 8x = 18x + 5
• 8x + 45 = 18x + 5
• 18x - 8x = 45 - 5
• 10x = 40
• x = 4

#10

• 15x + 5 + 22x + 4 = 120
• 37x + 9 = 120
• 37x = 111
• x = 3
