mohon bantuannya,berikan cara pengerjaan beserta jawabannya

|x + 1| - |-6x| = x - 9
|x + 1| - |6x| = x - 9
(i)
x + 1 - 6x = x - 9
-6x = -10
x = 10/6
x = 5/3

(ii)
x + 1 - 6x = -(x - 9)
x + 1 - 6x = -x + 9
x + x - 6x = 8
-4x = 8
x = 8/-4
x = -2

nilai x yang memenuhi x = -2   atau   x = 5/3
jadi HP : {-2, 5/3}
