2) (x-5)/5 ≥ (x-4)/2 + 1 —> kalikan dgn 102(x-5) ≥ 5(x-4) + 10
2x - 10 ≥ 5x - 20 + 10
- 3x ≥ 0
3x ≤ 0
x ≤0
3) | 3|-2| - 10 | = | 3.2 - 10 | = | - 4 | = 4
4) |5x-6| - 4 = 10
|5x-6| = 14
5x - 6 = 14 atau - (5x-6) = 14
5x = 20 atau - 5x + 6 = 14
x = 4 atau x = - 8/5 = - 1 3/5
HP = { 4, - 1 3/5}
5) |6x-13| > 5
6x-13 > 5 atau 6x-13 < - 5
6x > 18 atau 6x < 8
x > 3 atau x < 4/3
