Please answer my question quickly if you can answer it in less that 30 minutes. I PROMISE I will give thumbs up

This is operation research course

these are sub question , as far as i know if i have one main question, and bellow sub question that is fine Qa till Qf are sub questions

Consider the following LP problem. Maximize 2= 3x + xy + 2x subject to *,. ** 2x, 520 2x + x, X510 and *, 20, x 20 x zo. Let x, and X, denote tie stack variables for the respective constraints.
