What value of s is a solution to this equation?

To solve the equation \( 22 = -7s + 9s \), we can first simplify the right side:

\[ -7s + 9s = (9 - 7)s = 2s \]

So the equation becomes:

\[ 22 = 2s \]

Next, we can solve for \( s \) by dividing both sides by 2:

\[ s = \frac{22}{2} = 11 \]

Thus, the value of \( s \) that is a solution to the equation is:

\[ \boxed{11} \]
