Question

Simplify m - {n - [p + (m + n - p)]}.
0
2m
-2m + 2p

Answer 1

First distribute the first negative sign and remove the {}.

m - n + [p + (m + n - p)]

Distribute the positive sign before the [ and remove the []

m - n + p + (m + n - p)

Distribute the positive sign before ( and remove the ()


m - n + p + m + n - p

Group like terms, i.e. (m with m , n with n and p with p).

(m + m) + (n - n) + (p - p) = 2m + 0 + 0 = 2m

hope that helps! :)!

Answer 2

yes it does tthanks

Answer 3

or m - {n - [p + (m + n - p)]}
= m -{n - [p + m + n - p]}
= m - {n - p - m - n + p}
= m - n + p + m + n - p
= 2m
