What are the Interval Notation of 2x/(x-4)-1 ≥-1
~~~~~~~~~~~~~~~~~~~~~~~~

In his post, @lwsshar3 produced the answer (-∞, 0] U [4, ∞).

In this form, the answer is incorrect.

The correct answer is (-∞, 0] U (4, ∞).

Find the difference.

(Hint: the difference is that number '4' is not in the solution set.)
