I can't seem to find a good way of solving this sort of congruence for x:

x^2 / 3 + 11 [itex]\equiv[/itex] 5 (mod x)

Through trial and error it appears at least 3 and 6 are answers, but how can you reach them regularly? (I'm heard conflicting things about fractions being defined for modular arithmetic. It might be that this isn't even a createable congruence.)
