B = {1, 2, 3, 6, 9, 18}

___________

Ix - 1I < 3

-3 < x - 1 < 3

-2 < x < 4

C = {-1, 0, 1, 2, 3}

_____________

D = {-16, -14, -12, -10, -8, -6, -4, -2, 0, 2}

_____________

I2x - 1I < 19

-19 < 2x - 1 < 19

-18 < 2x < 20

-9 < x < 10

E = {-6, -3. 0, 3, 6, 9}

x + 2 = 1

x = 1 - 2 = -1

x + 2 = 13

x = 13 - 2 = 11

F = {-1, 11}
