Solution Steps

Step 1: Isolate the Variable \( r \)

To solve for \( r \) in the equation \( K = 9r - s \), we need to isolate \( r \) on one side of the equation. Start by adding \( s \) to both sides:

\[ K + s = 9r \]

Step 2: Solve for \( r \)

Now, divide both sides of the equation by 9 to solve for \( r \):

\[ r = \frac{K + s}{9} \]

Final Answer

The solution for \( r \) is:

\[ \boxed{r = \frac{K + s}{9}} \]
