Use the simplex algorithm to find the optimal solution to the following LP:

 

The given image presents a linear programming problem for minimization. The objective is to minimize the function \( z \) which is expressed as:

\[ \text{min } z = 4x_1 - x_2 \]

This is subject to the following constraints:

1. \( 2x_1 + x_2 \geq 8 \)
2. \( x_2 \leq 5 \)
3. \( x_1 - x_2 \leq 4 \)
4. \( x_1, x_2 \geq 0 \)

Here, \( x_1 \) and \( x_2 \) are the decision variables, and the goal is to find their values that minimize \( z \) while satisfying all the constraints.
