Tolong bantuu jawabb no 1 2 4 pake caraa .

1. 7|3x-4| = 35
|3x-4| = 35 : 7
|3x-4| = 5
3x = 5+4
3x = 9
X = 3

2. 2 | x-8| - 15 = 1
| x-8 | = 1+15
|x-8| = 16:2
|x-8| = 8
X = 16

4. | x + 1 | - 15 >= -10
|x+1| >= -10+15
|x+1| >= 5
X+1 >= 5 atau x+1 <= -5
X >= 4 atau x <= -6
*no 4 lupa2 gitu
Maaf kl salah
