it depends on where X is.
and what does "13 of the way" even mean?
What are the coordinates of Y if (5, 12) is 13 of the way from X to Y?

its 15,36
If you meant to say that the point (5,12) lies 13 of the way between X and Y, then more information is needed about the location of X to determine the coordinates of Y.
However, if you meant that the distance between the points X and Y is 13 units and the point (5,12) lies on the line segment connecting them, then there could be multiple possible coordinates for point Y.
