Answer:

1) x/4 < 4 ⇒ x < 4*4 ⇒ x< 16

  • x = 4, 8, 12

2) x + 3 ≥ 15 ⇒ x ≥ 12

  • x = 12

3) 19 > x + 4 ⇒ 15 > x ⇒ x < 15

  • x = 4, 14

4) 12 ≥ 6x ⇒ 2 ≥ x ⇒ x ≤ 2

  • x = 1, 2

5) 7x ≤ 21 ⇒ x ≤ 3

  • x = 1, 2, 3

6) 5 + x < 7 ⇒ x< 2

  • x = 1

7) x - 5 < 17 ⇒ x < 22

  • x = 9, 14, 15

8) 3x ≥ 18 ⇒ x ≥ 6

  • x = 6, 11

9) 20 > x + 9 ⇒ 11 > x ⇒ x < 11

  • x = 4, 8
