But actually in your case n+13/3n-1 can be a negative integer up to -4, so it doesn't have to be a natural number
What I had got after some algebra was: x = (7n+3)/(3-n) which needs to be a natural number, like you said. Then, since the numerator is always positive the denominator needs to be positive too, so n < 3. Then both n=1 and n=2 work we got different results though, but that may be me because I'm sloppy with algebra
