soal mtk cara cariknya

jawab

(1)
|5 - 2x| ≤  3

-3 ≤  5 -2x  ≤  3
- 3 - 5   < - 2x ≤  3 - 5
-8 < -2x < -2

-2x < - 2
x > 2

--2 x > - 8
x < 4

HP = 2 < x < 4


(2)
|x + 3 | > | 6 - 2x|
(x + 3)² - (6- 2x)² < 0
(x+3+ 6 - 2x) - (x+ 3-6+2x) < 0
(9 - x) (-3 + 3x) < 0
x < 9  atau x > - 1
HP= -1 < x < 9

(3)
|3x - 3|> 6
-6 > 3x - 3 > 6
-6 + 3 > 3x > 6+ 3
- 3 > 3x > 9

3x > 9
x > 3

3x < -3
x < -1

hp  x < -1  atau x > 3
