$(1$ point$)$

Evaluate the following limit by simplifying the expression $($first answer box$)$ and then evaluating the limit $($second answer box$).$

$\underset{x4}{lim}(\frac{\frac{1}{x}-\frac{1}{4}}{x-4})=\underset{x4}{lim}$

$$

Note: In your written solution, you should write the limit statement $\underset{x4}{lim}$ in every step except the last one, where the limit is finally evaluated.
