you can start by subtracting 5 from both sides, getting
|x-5|<3

sorry i was going to answer but dimbeni looks like he got it! :)
OpenStudy (anonymous):
ok thanks xokatexo
OpenStudy (anonymous):
your welcome<3
OpenStudy (anonymous):
then you split it in two:
when |x-5| >0, it becomes x-5<3, i.e.
x-5>0 AND x-5<3
x>5 AND x<8
5<x<8

when x-5<=0, it becomes -x+5<3, i.e.
x<=5 AND x>2
2<x<=5
OpenStudy (anonymous):
Finally, you join the two sets, getting
2<x<8
OpenStudy (anonymous):
where did the 8 come from?
OpenStudy (anonymous):
first part, when you have x-5<3, add 5 on both sides
OpenStudy (anonymous):
oh ok I forgot about the 8
