Lengkap.

Answer 1

Verified answer

Sistem Pertidaksamaan Linear Satu Variabel

5 ≤ 2x - 3 ≤ 13

5 ≤ 2x - 3 ∩ 2x - 3 ≤ 13
8 ≤ 2x ∩ 2x ≤ 16
x ≥ 4 ∩ x ≤ 8
4 ≤ x ≤ 8

HP : {x | 4 ≤ x ≤ 8 , x ∈ R}

Answer 2

==Jawaban==

13 ≥ 2x - 3 ≥ 5
13 + 3 ≥ 2x ≥ 5 + 3
16 ≥ 2x ≥ 8
16/2 ≥ x ≥ 8/2
8 ≥ x ≥ 4
4 ≤ x ≤ 8

Hp = {x| 4 ≤ x ≤ 8}
