Jawaban:
Contoh 1
Tentukanlah HP |2x – 1| = |x + 4|
Jawaban :
|2x – 1| = |x + 4|
2x – 1 = x + 4 ataupun 2x – 1 = -(x + 4)
x = 5 ataupun 3x = -3
x = 5 ataupun x = -1
Maka, HP = (-1, 5)
Contoh 2
Tentukanlah himpunan penyelesaian |2x – 7| = 3
|2x – 7| = 3 ( 2x – 7 = 3 ataupun 2x – 7 = -3)
|2x – 7| = 3 ( 2x = 10 ataupun 2x = 4)
|2x – 7| = 3 ( x = 5 ataupun x = 2)
Maka, HP = 2, 5
