tentukan hp dari -5 |×-7|+2=-13

Jika soal ↓
-5(x - 7) + 2 = -13
-5x + 35 + 2 = -13
-5x = -13 - 37
x = -50 / -5
x = 10
HP {10}

jika soal ↓
-5 |x - 7| + 2 = -13
-5 |x - 7| = -13 - 2
|x - 7| = -15 : -5
(x - 7)² = 3²
x² - 14x + 49 - 9 = 0
x² - 14x + 40 = 0
(x - 10)(x - 4) = 0
x = 10 dan x = 4

HP {10 , 4}

Semoga berguna +_+

Pembahasan :
-5|x - 7| + 2 = -13
-5|x - 7| = -15
|x - 7| = 3

x - 7 = 3
x = 3 + 7
x = 10

x - 7 = -3
x = -3 + 7
x = 4

Hp : {4 , 10}
