(4 − 2x)−2

how do you solve this? i have solved it and gotten 6 for my answer many times and it says it's wrong.
other equations are (y − z)−3 and (x − 5y)0. i cant get them right

    First, please proofread your post. It appears you are trying to solve

    4-2x = -2
    y - z = -3
    x - 5y = 0

    But that does not appear to fit the other data. How is the question actually presented?

    Write your 3 equations exactly, and then we can make some progress.
