Solve the system of inequalities graphically :`3x+2ylt=150 ,x+4ylt=80 ,xlt=15 ,ygeq0`.

Explanation

To solve the system of inequalities graphically, we will follow these steps:

### Step 1: Write down the inequalities
The inequalities we need to solve are:
1. \(3x + 2y \leq 150\)
2. \(x + 4y \leq 80\)
3. \(x \leq 15\)
4. \(y \geq 0\)
