Find the area of the triangle formed by the lines `y = x, y= 2x, y=3x+4`

Explanation

To find the area of the triangle formed by the lines \( y = x \), \( y = 2x \), and \( y = 3x + 4 \), we will follow these steps:

### Step 1: Find the intersection points of the lines.

1. **Finding Point A (Intersection of \( y = x \) and \( y = 3x + 4 \))**:
- Set \( y = x \) equal to \( y = 3x + 4 \):
\[
x = 3x + 4
