???????????? solushun set ???????????????
abs(2x-1) < 5 is a equashun
step 1...abs(2x-1)=5
1 posabel anser is (2x-1)=5...2x=6, or x=3
or (2x-1)=-5, so 2x=-4 & x=-2
suspekt anser is -2 < x < 3
tri x=0...abs(2*0-1)=1 so it agree with abs(2x -1) <5
tri x=5, abs(2x-1)=9 wich is not anser
so it look like good anser
