Answer 2

Answer:

p - (p - q) - (q -p) -q

= p - p + q - q + p - q

= p - q

Step-by-step explanation:

minus sign is common in p - q and in q - p so we will multiply minus.

hence it will come - p + q - q + p

- p and + p will get cancel and + q and - q will also get cancel, the remaining is p and - q

Hence, the answer will be p - q
