Question: Use Solver to solve the problem:

Maximize: Z = 1x₁ + 1x₂

Subject to: 1x₁ + 2x₂ £ 6

6x₁ + 4x₂ £ 24

3x₁ +3x₂ ³ 21

x₁ , x₂ ³ 0

a. Can this problem be solved? If so, what is the optimal solution? If not, what is the problem?

b. What would the solution be if the third constraint were removed from the problem?
