What is this egyptian fraction?I'd like to know about it.

Hi John-o;

There are a lot of solutions to that equation. Are there any constraints you have left out?

We can treat this with a few more constraints as an Egyptian fraction. One possible solution is

So we have a=1 and ab -1 =14 and b = 15

Substituting into the top equation:

x = 15 , y = 210 is one solution.

There 5 solutions with positive integers and x ≠ y. They are

For a general solution that gets all solutions

All solutions are now generated by adding 14 to the divisors of 196.
