suppose we have the following LPP
Maximize Z = - 2x_{1} - x_{2}

s.t. 3x_{1} + x_{2} = 3

4x_{1} + 3x_{2} >= 6x_{1} + 2x_{2} <= 3
x_{1}, x_{2} >= 0



Let's break down the Linear Programming Problem (LPP) you provided:

### Objective Function:
Maximize \( Z = -2x_1 - x_2 \)

### Constraints:
1. \( 3x_1 + x_2 = 3 \)
2. \( 4x_1 + 3x_2 \geq 6 \)
3. \( 6x_1 + 2x_2 \leq 3 \)
4. \( x_1, x_2 \geq 0 \) (non-negativity constraints)

### Steps to solve this LPP:
1. **Convert the inequalities into standard form**:
    - For the second constraint: \( 4x_1 + 3x_2 \geq 6 \), we convert it into a slack variable \( s_1 \) as:
      \[
      4x_1 + 3x_2 - s_1 = 6 \quad \text{where } s_1 \geq 0.
      \]
    - For the third constraint: \( 6x_1 + 2x_2 \leq 3 \), we convert it into a surplus variable \( s_2 \) as:
      \[
      6x_1 + 2x_2 + s_2 = 3 \quad \text{where } s_2 \geq 0.
      \]
2. **Set up the initial tableau** and solve using either the graphical method (for 2 variables) or the simplex method if desired.

Since your objective function is to maximize a **negative** value, the solution may involve minimizing the negative value for optimality. Would you like me to proceed by solving this using the Simplex method step by step, or prefer a graphical interpretation for visualization?

Let me know if you'd like more detailed solutions or have any questions. Meanwhile, here are 5 related questions for exploration:

1. How do you determine feasibility in a Linear Programming Problem?
2. Can you explain how slack and surplus variables affect the LPP's solution space?
3. What happens if the objective function is maximized but gives a negative result?
4. How does non-negativity constraints affect the solution of LPPs?
5. Could you solve this problem graphically by plotting the constraints?

**Tip**: When maximizing or minimizing an objective function, always check if your constraints form a feasible region first!
