Find the value of p so that the three lines `3x + y - 2 = 0`, `p x + 2 y - 3 = 0`and `2x -y -3 = 0`may intersect at one point.

Explanation

To find the value of \( p \) such that the three lines \( 3x + y - 2 = 0 \), \( p x + 2 y - 3 = 0 \), and \( 2x - y - 3 = 0 \) intersect at one point, we need to determine the condition for these lines to be concurrent. This can be done using the determinant method.

### Step-by-Step Solution:

1. **Identify the coefficients**:
- For the first line \( 3x + y - 2 = 0 \):
- \( a_1 = 3, b_1 = 1, c_1 = -2 \)
- For the second line \( p x + 2 y - 3 = 0 \):
