Find the value of `m` for which the lines `m x+(2m+3)y+m+6=0a n dm x+(2m+1)x+(m-6)y+9=0` intersect at a; point on `y-a xi sdot`

Explanation

To find the value of \( m \) for which the lines intersect at a point on the y-axis, we will follow these steps:

### Step 1: Write down the equations of the lines
The equations of the lines are given as:
1. \( mx + (2m + 3)y + (m + 6) = 0 \)
2. \( mx + (2m + 1)x + (m - 6)y + 9 = 0 \)

### Step 2: Substitute \( x = 0 \) into both equations
