1. 3|x-1|=6
|x-1|=6/3
|x-1|=2
*x-1=2
x=3
*x-1=-2
x=-1
Jadi Hp {x=3 dan x=-1}
2. |2x+16|=x+4
*(2x+16)-(x+4) *-(2x+16)=x+4
x=-12 -2x-16=x+4
-2x-x=4+16
-3x=20
x=-20/3
Jadi HP {}
3. |2x+1|-2=3
|2x+1|=3+2

*2x+1=5 *2x+1=-5
2x=5-1 2x=-5-1

x=4/2 x=-6/2
x=2 x=-3
Jadi HP {x=2 dan x=-3}
4. |2x+1|-x=11
*2x+1-x=11 *2x+1-x=-11
2x+x=11-1 2x-x=-11-1
x=10 x=-12
Jadi HP {x=10 dan x=-12}

Jadi HP {x=-1 dan x=13/5}
