### Linear Programming Problem

This example illustrates a typical linear programming problem where the objective is to maximize a given function subject to certain constraints.

**Objective Function:**

\[ z = 14x_1 + 3x_2 \]

**Subject to the constraints:**

\[ 7x_1 + 3x_2 \leq 8 \]

\[ x_1 + 3x_2 \leq 4 \]

\[ x_1 \geq 0, \quad x_2 \leq 0 \]

### Explanation:

1. **Objective Function:**
- The function $ z = 14x_1 + 3x_2 $ is the objective function we aim to maximize.
- $ x_1 $ and $ x_2 $ are the decision variables that affect the value of $ z $.

2. **Constraints:**
- The first constraint $ 7x_1 + 3x_2 \leq 8 $ limits the possible values of $ x_1 $ and $ x_2 $ to ensure that their combination does not exceed 8.
- The second constraint $ x_1 + 3x_2 \leq 4 $ sets another limit, restricting the combination of values of $ x_1 $ and $ x_2 $ to not exceed 4.
- Additionally, $ x_1 \geq 0 $ ensures that $ x_1 $ is non-negative.
- $ x_2 \leq 0 $ specifies that $ x_2 $ must be non-positive (zero or a negative number).

### Purpose:
This type of problem is fundamental in operations research and economics, helping in making the best possible decisions within given limitations. The goal is to find the values of $ x_1 $ and $ x_2 $ that maximize $ z $ while satisfying all the constraints. These problems are typically solved using methods such as the Simplex algorithm or graphical methods for two-variable cases.
