For the linear programming problem:

$$\begin{array}{ll} \text{Maximize}  & Z = 3X_1 + 2X_2 \\ \text{Subject to} &−2X_1 + 3X_2 \leq 9\\  & X_1 − 5 X_2 \geq −20   \\ & X_1, X_2 \geq 0 \end{array}$$ 

The above problem has

  1. unbounded solution
  2. infeasible solution
  3. alternative optimum solution
  4. degenerate solution
