create four pairs of equivalent expressions

Question

given
p+p
5p+2p-p
5p-4p
2p-p
4p
4p-2p
3p
6p
5p
2p+p

Answer 1

Here are four pairs of equivalent expressions based on the given expressions:

1. \( p + p \) and \( 2p \)
2. \( 5p + 2p - p \) and \( 6p \)
3. \( 5p - 4p \) and \( p \)
4. \( 2p - p \) and \( p \)

These pairs show equivalent expressions after simplification.
