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

    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

    Finally, you join the two sets, getting 2<x<8

    first part, when you have x-5<3, add 5 on both sides
