To which I reply:
There is only one answer possible, but I am not sure this is
really what you want.  The answer is

x = (15Y + sqrt( (15Y)^2 -240Y ) ) / 10Y

for the more positive root, and

x = (15Y + sqrt( (15Y)^2 -240Y ) ) / 10Y

Of course, depending on your value for Y, the answers might
be complex numbers.
