Answer:
-9m+5n+2p
Step-by-step explanation:
first we add:
13m-11n+9p+(-7p+3m-5n)
13m-11n+9p-7p+3m-5n
13m+3m-11n-5n+9p-7p
= 16m-16n+2p
6m-7n-5p-4m+6p-9n+5m-4n+3p
6m-4m+5m-7n-4n-5p+6p+3p
2m+5m-11n+1p+3p
= 7m-11n+4p
Now we solve
7m-11n+4p-(16m-16n+2p)
7m-11n+4p-16m+16n-2p
7m-16m-11n+16n+4p-2p
= -9m+5n+2p
