Jika + 2 :
x - 5 = 2
x = 2 + 5
x = 7

Jika - 2 :
x - 5 = -2
x = - 2 + 5
x = 3

Hp = { 3 , 7 }

Semoga membantu ... semangat ^_^

3|x - 5| - 4 = 2
3|x - 5| = 2 + 4
3|x - 5| = 6
|x - 5| = 6 ÷ 3
|x - 5| = 2

x - 5 = 2     atau     x - 5 = -2
x = 2 + 5    atau     x = -2 + 5
x = 7          atau     x = 3
