1. Jawaban Darksimple
a -5 |x - 7| + 2 = -14
-5 |x - 7| = -14 -2
-5 |x - 7| = -16
|x - 7| = -16/-5
|x - 7| = 16/5
|x - 7| = -16/-5
x = -16/-5 + 7
x = -16/-5 + -35/-35
x = -112/-35 + -35/-35
x = -147/-35
|x - 7| = 16/5
x = 16/5 + 7
x = 16/5 + 35/35
x = 112/35 + 35/35
x = 147/35
HP = {-147/-35, 147/35}
