|x-1|=|x+7|

Mohon bantuannya ​

Penjelasan dengan langkah-langkah:

|x - 1| = |x + 7|

(x - 1)² = (x + 7)²

(x - 1)² - (x + 7)² = 0

((x - 1) + (x + 7))((x - 1) - (x + 7) = 0

(x - 1 + x + 7)(x - 1 - x - 7) = 0

(2x + 6)(-8) = 0

(2x(-8) + 6(-8)) = 0

-16x - 48 = 0

-16x = 0 + 48

-16x = 48

x = 48/-16

x = -3
