Question: Assume that you are solving the following LP model using Two-phase method. Max x1 + x2 s.t. x1 + x2 = 15 X1, x2 >=

Assume that you are solving the following LP model using Two-phase method.

Max x1 + x2

s.t.

x1 + x2 <= 1

3x1 + 5x2 >= 15

X1, x2 >= 0

This LP model is either infeasible or unbounded. Is this model infeasible or unbounded? How did you identify it if this model is infeasible or unbounded from the Two phase method tableau.
