Va rog, am nevoie urgent

Answer 1

Răspuns:

Explicație pas cu pas:

3x + 17 < x - 13

3x - x < -13 - 17

2x < -30

x < -15

_______________

4(2 - 3x) + 3(4 - 2x) ≥ 0

8 - 12x + 12 - 6x ≥ 0

20 - 18x ≥ 0

18x ≤ 20

x ≤ 20/18

x ≤ 10/9

________________

3(2x - 1) + 5 ≤ 2x + 7

6x - 3 + 5 ≤ 2x + 7

6x + 2 ≤ 2x + 7

6x - 2x ≤ 7 - 2

4x ≤ 5

x ≤ 5/4

_______________

(3x - 2)/4 - (5x - 1)/3 > 1

3(3x - 2) - 4(5x - 1) > 12

9x - 6 - 20x + 4 > 12

-11x - 2 > 12

11x < -2 -12

11x < -`14

x < -14/11
