Question 1202304
<pre>
Two of the above are incomplete because there are two solutions. 
Mine (the second one) is the only complete one.
Ikleyn mistook the problem as requiring that the solution be integers.
That was not necessary and caused the second solution to be lost.

The trick to making the algebra simpler was to use the smaller as x
and the larger as x+k where k > 0
