Find the line of best fit for the following data, treating $x$ as dependent variable (Regression equation $x$ on $y$):
Hence, estimate the value of $x$ when $y = 16$.
| $X$ | 14 | 12 | 13 | 14 | 16 | 10 | 13 | 12 |
|---|---|---|---|---|---|---|---|---|
| $Y$ | 14 | 23 | 17 | 24 | 18 | 25 | 23 | 24 |
