Issue with a problem. Not clear if I should use Maxwell or Gauss. HELP

Nov 2019

This is my first post so Im really new at this posts, I hope im bringing enough context to this problem.
I've tried to resolve it by using Maxwell equations or Gauss Laws but Im frankly lost at this point, any input will be much appreciated.

A wire of very large length, has a charge density λ +, distributed continuously and constantly.
At a distance d , a wire of length l is placed perpendicularly, with a total load q- distributed continuously and constantly.
