6<x<8 is definitely correct, at least up to beyond degree-level maths
This is the combination of two equations x>6 and x<8.
x>6 is equivalent to 6<x (note the switch of the sign in the middle) so you have 6<x and x<8. And, x being equal to x, means you can combine the two 'equations' into a single 6<x<8.
So, yes, it depends on the context. The context here being x.
If my car was less than 6, I would say 'my car <6'. You could also say '6> my car', but that's a bit clunky. Like the car.
(NB Assuming x is in the set of natural numbers or integers, x=7, otherwise it could be anything in between. )
