Răspuns:

Explicație pas cu pas:

-18 < x ≤ 2

x = {-17, -16, -15, -14, -13, -12, -11, -10, -9, -8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2}

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

______________

I2x - 1I < 19

-19 < 2x - 1 < 19

-18 < 2x < 20

-9 < x < 10

x = {-8, -7, -6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

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