Mapel : Matematika
Kelas : X SMA
Materi : Persamaan Nilai Mutlak

Pembahasan :
Jika soal ↓
2x + |3x - 8| = -4
|3x - 8| -4 - 2x
(3x - 8)² = (-4 - 2x)²
(3x - 8)² - (-4 - 2x)² = 0
(x - 12)(5x - 4) = 0
x = 4/5
x = 12

Hp : {4/5 , 12}

————————————————
x + |8 - 3x| = -4
|8 - 3x| = -4 - x
(8 - 3x)² = (-4 - x)²
(8 - 3x)² - (-4 - x)² = 0
(-4x + 4)(-2x + 12) = 0
x = 1
x = 6

Hp : {1 , 6}
