How do I go about doing this programming problem??

Sketch the region of feasibility and solve the linear programming problem:

Maximize C = 4x-5y, subject to:

x ≥ 2

y ≥ 0

x + y ≤ 7

X + 2y

What does this mean?

Any Formulas I could use?

I can probably sketch the region of feasibility, but how do i solve?

Thanks so much.
