Bab Nilai Mutlak
Matematika SMA Kelas X

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

2x - 3 = 8
2x = 8 + 3
x = 11/2

2x - 3 = -8
2x = -8 + 3
x = -5/2

HP = { -5/2, 11/2 }

Persamaan Nilai Mutlak

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

Menurut definisi , |x| = a atau -a

2x - 3 = 8
2x = 8+3
2x = 11
x = 11/2

--------------

2x - 3 = -8
2x = -8+3
2x = -5
x = -5/2
