Explicación paso a paso:

)

\begin{gathered}(3a+2b-c) +(2a+3b+c)\\=3a+2b-c+2a+3b+c\\=5a+5b\end{gathered}(3a+2b−c)+(2a+3b+c)=3a+2b−c+2a+3b+c=5a+5b

b)

\begin{gathered}(7a-4b+5c) + (-7a+4b-6c)\\=7a-4b+5c-7a+4b-6c\\=-c\end{gathered}(7a−4b+5c)+(−7a+4b−6c)=7a−4b+5c−7a+4b−6c=−c

c)

\begin{gathered}(m+n-p)+(-m-n+p)\\m+n-p-m-n+p\\0\end{gathered}(m+n−p)+(−m−n+p)m+n−p−m−n+p0

d)

\begin{gathered}(9x-3y+5)+(-x-y+4)+(-5x+4y-9)\\9x-3y+5-x-y+4-5x+4y-9\\3x\end{gathered}(9x−3y+5)+(−x−y+4)+(−5x+4y−9)9x−3y+5−x−y+4−5x+4y−93x

e)

\begin{gathered}(a+b-c)+(2a+2b-2c)+(-3a-b+3c)\\=a+b-c+2a+2b-2c-3a-b+3c\\=2b\end{gathered}(a+b−c)+(2a+2b−2c)+(−3a−b+3c)=a+b−c+2a+2b−2c−3a−b+3c=2b
