    Actually there are two answers: - 3 and 0, depending on how the expression is written.

    Step-by-step explanation:

    If the rational expression is x - 4/x - 6, we have:

    x - 4/x - 6

    = 4 - 4/4 - 6

    = 4 - 1 - 6 = 4 - 7 = - 3

    If the rational expression is (x - 4) / (x - 6), we have:

    (x - 4) / (x - 6)

    = (4 - 4) / (4 - 6)

    = 0/-2 = 0
