Answer 1

Answer:

-10p will be right answer

Step-by-step explanation:

AFTER THE SUM OF BOTH THEIR DIFFERENCE WILL BE

2p+q-r-12p-q+r

=-10p

Answer 2

Step-by-step explanation:

Sum of 11p+q and p-r = 11p+q+p-r

= 11p+p+q-r

= 12p+q-r

And sum of p-2r and p+q+r = p-2r+p+q+r

= p+p-2r+r+q

= 2p-r+q

Subtracting:-

2p-r+q-(12p+q-r)

2p-r+q-12p-q+r

2p-12p-r+r+q-q

-10p
