Solve it in simplex and use gormory cutting plane method

To solve the linear programming problem using the simplex method followed by the Gomory cutting plane method, let's first interpret the problem from the image.

### Problem Interpretation:
You have a linear programming problem that you need to solve using the simplex method:

**Objective Function:**
Maximize \( Z = 3x_1 + 2x_2 \)

**Subject to the constraints:**
\[
x_1 + x_2 \leq 5
\]
\[
2x_1 + x_2 \leq 6
\]
\[
x_1, x_2 \geq 0
\]

### Step 1: Solve Using Simplex Method
Let's start by solving the linear programming problem using the simplex method.

1. **Convert the inequalities into equations by adding slack variables:**

\[
x_1 + x_2 + s_1 = 5
\]
\[
2x_1 + x_2 + s_2 = 6
\]

Here, \(s_1\) and \(s_2\) are slack variables, and they are non-negative.

2. **Set up the initial simplex tableau:**

\[
\begin{array}{c|cc|cc|c}
 & x_1 & x_2 & s_1 & s_2 & \text{RHS} \\
\hline
\text{Equation 1} & 1 & 1 & 1 & 0 & 5 \\
\text{Equation 2} & 2 & 1 & 0 & 1 & 6 \\
\hline
\text{Objective} & -3 & -2 & 0 & 0 & 0 \\
\end{array}
\]

3. **Perform the simplex method iteration:**

   - Identify the entering variable (most negative coefficient in the objective row).
   - Identify the leaving variable (smallest positive ratio of RHS to the coefficient of the entering variable).
   - Perform pivoting.

4. **Continue iterations until no negative coefficients are left in the objective row.**

### Step 2: Apply Gomory Cutting Plane Method (if needed)
If the optimal solution obtained from the simplex method is not an integer, apply the Gomory cutting plane method to find an integer solution. The steps generally include:

1. **Identify fractional values in the final tableau.**
2. **Generate a cutting plane (Gomory cut) from the fractional row.**
3. **Add the cut to the tableau and re-optimize using the simplex method.**
4. **Repeat until all variables are integers.**

### Solution Outline:
1. Solve the linear program using the simplex method to find the optimal solution.
2. If the solution is not integer, use the Gomory cutting plane method to convert it to an integer solution.
