    No. Try numbers

    Let x = 7

    20 - 7 = 13

    4 - 7 = 3.

    These do not reduce any further. If you try it like (5 - x)/-x

    Almost no value will be the same as the beginning. For example x = 10

    20 - x = 20 - 10 = 10

    4 - x = 4 - 10 = -6

    10/-6 = - 1 2/3

    Now try your canellation

    5 - 10 = - 5

    - x = - 10

    -5/-10 = 1/2

    Yep:) 20/4 (or 20 over 4) is the same as 20 divided by 4. That equals 5, so any division that equals 5 can be used XD 20/4 = 10/2 = 5/1. Just put for x's in:))

    edit- where all reading this differently! Depends whether it's 20 - x ( 20 minus X) - then no! But if it's 20x then yea:)

    Source(s): Hope thats what you meant!

    NO! (20-x) over (4-x) does NOT reduce
