1. -5 |3x-7| + 4 = 14 2. |4x-8| = 0 3. |2x-1| = |x+3| Tolong dibantu sama jalan nyari x nya ya ... please jangan asal. Thank you

1.
-5 | 3x - 7 | + 4 = 14
-5 | 3x - 7 | = 10
| 3x - 7 | = -2
tidak ada penyelesaian, karena semua bilangan mutlak selalu bernilai positif

2.
| 4x - 8 | = 0

4x - 8 = 0
4x = 8
x = 2

-(4x - 8) = 0
-4x + 8 = 0
4x = 8
x = 2

Hp = {2}

3.
| 2x - 1 | = | x + 3 |

2x - 1 = x + 3
2x - x = 3 + 1
x = 4

-(2x - 1) = x + 3
-2x + 1 = x + 3
x + 2x = 1 - 3
3x = -2
x = -2/3

Hp = {-2/3 , 4}
