Materi : Nilai Mutlak
Bahasan : Persamaan Nilai Mutlak
Jawaban : x = 4 atau x = -1

Langkah - langkah :
|f(x)| = a, f(x) = a atau f(x) = - a
|2x - 3| = 5
⇒ 2x - 3 = 5
2x - 3 = 5
2x = 5 + 3
2x = 8
x = 4

⇒ 2x - 3 = - 5
2x = - 5 + 3
2x = - 2
x = - 1

Bab Nilai Mutlak
Matematika SMA Kelas X

|2x - 3| = 5

2x - 3 = 5
2x = 5 + 3
x = 8/2
x = 4

2x - 3 = -5
2x = -5 + 3
x = -2/2
x = -1

HP = { -1, 4 }
