Show that the straight lines given by `(2+k)x+(1+k)y=5+7k` for different values of `k` pass through a fixed point. Also, find that point.

Explanation

To show that the straight lines given by the equation \((2+k)x + (1+k)y = 5 + 7k\) pass through a fixed point for different values of \(k\), we will rearrange the equation and find the point where these lines intersect.

### Step-by-step Solution:

1. **Start with the given equation:**
\[ (2+k)x + (1+k)y = 5 + 7k \]
