Wow, how bold of you, or how desperate are you to try me!!! Solve and write the set A ∩ B "A intersect B". You may use a Ven Diagram, List, partial list or rule.

Let U={integers}

Let A={x| 3(x-2)-7x<6}

Let B={x| 15 (x-3)+3x<45}

A ∩ B={x| -3<x<5}

         or

A ∩ B={-2,-1,0,...,4}

        or

A ∩ B={-2,-1,0,1,2,3,4}
