I am supposed to subtract and simplify if possible. This is backward to what we had in our homework so I am confused.

two fractions
4-z/z-3 minus 7z-6/3-z

I need to determine what z is?

    Your non use of parenthesis makes the problem hard to read, but I will guess it is this:

    (4-z)/(z-3) - (7z-6)/(3-z)

    1) notice that z-3= -(3-z)
    Then

    (4-z)/(z-3) +(7z-6)/(z-3)
    can you take it from here?

    12z+3z=15z?
