|x-1| = 6 menggunakan cara definisi nilai mutlak materi : penyelesaian PLSVNM

|x - 1| = 6
x - 1 = 6
x = 6 + 1
x = 7
x - 1 = -6
x = -6 + 1
x = -5
HP = {-5, 7}

Materi : Persamaan Mutlak

Pembahasan :
|x - 1| = 6
(x - 1)² = 6²
(x - 1)² - 6² = 0
(x - 1 + 6)(x - 1 - 6) = 0
(x + 5)(x - 7) = 0
x = -5
x = 7

Hp : {-5 , 7}
