1) |4x+5|=11
|4x+5|={4x+5 if 4x+5>0(4x+5) if 4x+5<0
4x+5=11(if 4x+5>0)
4x=115=6
x=64=32
(4x+5)=11(if 4x+5<0)
4x+5=11
4x=16
x=4
|4x+5|=11
Sx=[4]
2) |7x+6|=25
7x+6=25(if 7x+6>0)
7x=256=19
x=197
(7x+6)=25(if 7x+6<0)
7x+6=25
7x=31
x=317
There doesn't exist any solution over Z

3. |2x11|=20
2x11=20(if 2x11>0)
2x=31
x=312
(2x11)=20(if 2x11<0)
2x11=20
2x=9
x=92
There isnt
