-2|x-6|+4=12, tolong jawab dong

-2| x - 6 | + 4 = 12
-2| x - 6 | = 12 - 4
| x - 6 | = 8 : (-2)
(x - 6)² = (-4)²
x² - 12x + 36 = 16
x² - 12x + 20 = 0
(x - 10)(x - 2) = 0
x = 10 dan x = 2

HP {10 , 2}

Semoga berguna +_+

-2(x-6)+4 = 12
x-6 = 8/-2
x = -4 +6
x = 2

atau.
-2(-(x-6)) + 4 = 12
-2(-x+6) = 8
-x+6 = -4
-x = -10
x =10

Hp = {2, 10}
