Step-by-step explanation:

<em>Exterior angle is same as sum of remote interior angles.</em>
Solving for x in each case below.

<h3>#7</h3>

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

<h3>#8</h3>

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

<h3>#9</h3>

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

<h3>#10</h3>

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