Hint
 Comment 3 of 9 
There is a very elementary (D2) method for determining the triplet(s) and proving that no further triplets exist.
The method basically involves rearranging the terms in the first equation and due substitution into the second equation.
It is important in this connection to remember that none of F, G and H can be imaginary numbers.
