This is on Mathematical Linear Programming.

Find the optimal solution of the LP problem below using two phase method. Write the standard form first and then present your solution. Indicate if there are any special cases.

Maximize Z = x₁ - 7x₂ + 3x₃ + 3x₄

Subject to:

x₁+ 5x₂ - 6x₃ + 2x₄ 3

4x₁ - 2x₂ - 5x₃ + 4x₄ = 15

x₁ - x₃ - 9x₄ -8

x₁, x₃, x₄ 0, x₂ URS
