Tolong dijawab dan pakai cara penting!

1) |x - 2| = 3

a) x - 2 = 3 ===> x = 5
b) x - 2 = -3 ==> x = -1
    HP = {-1, 5}

2) |2x| = 6

a) 2 |x| = 6 ===> x = 3
b) 2 |x| = -6 ==> x = -3
    HP = {-3, 3}

3) |x + 5| = 2

a) x + 5 = 2 ===> x = -3
b) x + 5 = -2 ==> x = -7
    HP = {-7, -3}

semoga jelas dan membantu ya
