Answer:

  • as written: none
  • perhaps intended: 0

Explanation:

The expression written here is interpreted according to the Order of Operations as ...

8x -(5/6)x

This reduces to (7 1/6)x, which is defined for all real numbers.

__

Maybe you intended the expression ...

(8x -5)/(6x)

This expression is undefined where its denominator is zero, at x = 0.
