### Linear Programming Problem

#### 1) Solve the given linear programming problem using the table method.

**Objective:** Maximize \( P = 7x_1 + 6x_2 \)

**Subject to:**
- \( 3x_1 + x_2 \leq 21 \)
- \( x_1 + x_2 \leq 10 \)
- \( x_1 + 2x_2 \leq 12 \)
- \( x_1, x_2 \geq 0 \)

**Options for Maximum \( P \):**
- **A)** \( \text{Max } P = 66 \text{ at } x_1 = 6, x_2 = 5 \)
- **B)** \( \text{Max } P = 68 \text{ at } x_1 = 8, x_2 = 2 \)
- **C)** \( \text{Max } P = 65.5 \text{ at } x_1 = 5.5, x_2 = 4.5 \)
- **D)** \( \text{Max } P = 60 \text{ at } x_1 = 6, x_2 = 3 \)

---

#### 2) Convert the given i-system to an e-system using slack variables. Construct a table of all basic solutions of the e-system. Indicate whether each basic solution is feasible.

**Linear Inequality:** \( 9x_1 + 7x_2 \leq 63 \)

**Conditions:** \( x_1, x_2 \geq 0 \)

**Tables for Basic Solutions:**

- **A)** 
  - **Equation:** \( 9x_1 + 7x_2 + s_1 = 63 \)

  \[
  \begin{array}{c|ccc}
  & x_1 & x_2 & s_1 \\
  \hline
  (A) & 0 & 0 & 63 \\
  (B) & 0 & 7 & 0 \\
  (C) & 9 & 0 & 0 \\
  \end{array}
  \]
