2 |3x-8| =10 minta tolong agar dijawab yaa trimakasihh.

Matematika Wajib
Persamaan Mutlak X SMA

Pembahasan :
Cara 1

2|3x - 8| = 10
|3x - 8| = 5
(3x - 8)² = 5²
(3x - 8)² - 5² = 0
(3x - 8 + 5)(3x - 8 - 5) = 0
(3x - 3)(3x - 13) = 0
x = 13/3
x = 1

Hp : {1 , 13/3}

Cara 2

2|3x - 8| = 10
|3x - 8| = 5

3x - 8 = 5
3x = 5 + 8
3x = 13
x = 13/3

3x - 8 = -5
3x = -5 + 8
3x = 3
x = 1

Hp : {1 , 13/3}
