We can have two cass x > 0 or x ≤ 0. As x cannot be positive, it must be less than or equal to 0. According to the absolute value property, when x ≤ 0, then |x| = -x. Thus, we can substitute |x| with -x in the expression we have:

\(\frac{-|x| - 1}{x - 1} = \frac{-(-x) - 1}{x - 1} = \frac{x - 1}{x - 1} = 1\).­
