In the future, be careful with your capitalization. x is NOT the same thing as X and y is NOT the same thing as Y. I assume you meant them to be the same.
If y varies directly as x, then 
. Substitute your initial values of x and y, then solve for k. Once you have the coefficient of proportionality, k, then you can create a formula that will give you either of the variables given the other.

------
y = k/x
Solve for "k"::
16 = k/45
k = 720
------
Equation:
y = 720/x
----
Find x if y = 24
-----
24 = 720/x
---
x = 720/24
x = 30
