The given Linear Programming Problem (LPP) is:

### Objective:
Minimize \( Z = x_1 - 3x_2 + 3x_3 \)

### Subject to the constraints:
1. \( 3x_1 - x_2 + 2x_3 \leq 7 \)
2. \( 2x_1 + 4x_2 \geq -12 \) (This can be rewritten as \( 2x_1 + 4x_2 \geq -12 \))
3. \( -4x_1 + 3x_2 + 8x_3 \leq 10 \)
4. \( x_1, x_2, x_3 \geq 0 \)

We will convert this problem into standard form to apply the **Simplex Method**.

### Step 1: Convert inequalities to equalities by introducing slack variables.
- For the first inequality \( 3x_1 - x_2 + 2x_3 \leq 7 \), we add a slack variable \( s_1 \geq 0 \):
  \[
  3x_1 - x_2 + 2x_3 + s_1 = 7
  \]
- For the second inequality \( 2x_1 + 4x_2 \geq -12 \), we introduce a surplus variable \( s_2 \geq 0 \) (because of the \( \geq \) sign):
  \[
  2x_1 + 4x_2 - s_2 = -12
  \]
- For the third inequality \( -4x_1 + 3x_2 + 8x_3 \leq 10 \), we add a slack variable \( s_3 \geq 0 \):
  \[
  -4x_1 + 3x_2 + 8x_3 + s_3 = 10
  \]

### Step 2: Rewrite the objective function in terms of standard form.
We have the objective function to minimize:
\[
Z = x_1 - 3x_2 + 3x_3
\]
This is already in the proper form for the Simplex method.

### Step 3: Set up the initial simplex tableau.
The tableau will include the variables \( x_1 \), \( x_2 \), \( x_3 \), the slack and surplus variables \( s_1, s_2, s_3 \), and the right-hand side (RHS).

Would you like to proceed with constructing the simplex tableau and performing the Simplex algorithm steps, or would you prefer an explanation of the theory behind it first? Let me know!
