(B) Step $1$: Let $y = f(x) = \frac{2x - 1}{x + 5}$.Step $2$: Solve for $x$ in terms of $y$: $y(x + 5) = 2x - 1$.Step $3$: Expand and rearrange: $yx + 5y = 2x - 1 \implies yx - 2x = -5y - 1$.Step $4$: Factor out $x$: $x(y - 2) = -(5y + 1) \implies x = \frac{-(5y + 1)}{y - 2} = \frac{5y + 1}{2 - y}$.Step $5$: Replace $y$ with $x$ to get $f^{-1}(x) = \frac{5x + 1}{2 - x}, x 
eq 2$.

If $f(x) = \frac{2x - 1}{x + 5}, x \neq -5$ then $f^{-1}(x)$ is equal to
