9) x = 9

10) x = - 8

11) x = 7

Step-by-step explanation:

9)

(180 - 15x + 4) + 7x + 1 + 67 = 180

180 - 15x + 4 + 7x + 1 + 67 = 180

-15x + 4 + 7x + 1 + 67 = 0

-8x + 72 = 0

72 = 8x

x = 9

10)

100 = x + 108

100 - 108 = x

x = -8

11)

10x - 1 + 17x - 8 = 180

27x - 9 = 180

27x = 189

x = 7
