We can simplify the equation step by step. The equation given is:
\[ 9 + 9k = 9 + 14k - 5k \]
First, simplify the right side by combining the like terms:
\[ 14k - 5k = 9k \]
So, the equation becomes:
\[ 9 + 9k = 9 + 9k \]
Now, we can see that both sides of the equation are equal. This means the equation is true for all values of \( k \).
In conclusion, the solution is that the equation is valid for all \( k \).
