Linear programming - please help

I present the following integer linear programming challenge:

max(x1 + x2),
4x1 + 6x2 + x3 = 17,
x1 − x2 + x4 = 2,
xi ≥ 0, x1, x2 ∈ Z.

i. Determine the solution manually for the linear programming relaxation of the given problem, beginning with B = (x3, x4) as the initial feasible solution.

ii. Identify and elucidate a Gomory cut for the optimal solution of the
previously mentioned linear programming problem.

hi AlachimUI

Welcome to the forum.

From the graph it looks like (2,1) and (1,2) are two solutions.

That makes x3 = 3 x4 = 1 and x3 = 1 and x4 = 3

What happens if you start with x3 and x4 taking those values?
