Question

Himpunan penyelesaian dari 14 - 3(1 - x) ≤ x - 5

Answer 1

14 - 3(1- x ) ≤ x - 5
14 - 3 + 3x ≤ x - 5
11 + 3x ≤ x - 5
3x - x ≤ -5 - 11
2x ≤ -16
x ≥ -8
Hp = ( - 8, 0 )

Answer 2

14 - 3(1 - x) ≤ x - 5
14 - 3 + 3x ≤ x - 5
11 + 3x ≤ x - 5
3x - x ≤ -5 - 11
2x ≤ -16
x ≤ -16/2
x ≤ -8

Hp= {...,-10,-9.-8}
