(4 − 2x)−2
x=2
y=4
z=3
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
42x = 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.
