To find the value of \( x \), we first need to clarify the relationships among the variables given in your equations. It seems that \( S \), \( K \), and \( Y \) refer to some geometrical figures or segments. Generally, the equations could represent segments in a triangle or some other configuration.
You provided these equations:
1. \( SK = 13x - 5 \)
2. \( KY = 2x + 9 \)
3. \( SY = 36 - x \)
Assuming that these lengths are related such
