Subject: integral solutions Hello : I'm stuck with this problem . I wonder if anyone can help me on it ... thanks determine all pairs of integers (x,y) which satisfy the equation 6x^{2}  3xy  13x + 5y = 11 I got y= (6x^{2}13x+11)/(3x5) and i don't konw how to continue thank you very much david Hi David,Very well up to there. You can split it up further by dividing 6x^{2}13x+11 by 3x5 to get: Now, all you need to do is decide which integer values of x will make y an integer. Cheers,Claude
