I'm answering -3 anyway, cuz it's the right answer :-p
Having said that, if you really wanna impress your teacher, you could read http://en.wikipedia.org/wiki/Modular_arithmetic (which is probably quite a bit higher-level maths than he's asking you about - it might all seem very complicated!). If you specified for example that you were working in mod 10, then:
9+7=6 (mod 10), for example.
Basically the "mod 10" in brackets means that you're working in a number system where you can take away or add on multiples of 10, so in that system, 6=16=26 etc.
But yeah, I'm sure that's not what he meant!

It must be -3 or if you want only positive solutions then there is no solution

9+x = 6
x = -3
No other answer is possible
