Answer:
4p
Step-by-step explanation:
To simplify this expression, just add/subtract as normal.
3p + 2p - p
3p + 2p = 5p
5p - (1)p = 4p
4p is the simplified version of 3p + 2p - p.
Answer:
4p
Step-by-step explanation:
You have 3p + 2p - p
If there is a single alone p like on the end of the equation, it can be assumed that there is a 1 in front of it, even if it doesn't show it.
A letter variable that is alone means there's always like an invisible 1 in front. So, you have:
3p + 2p - 1p
Subtract 1p from 2p to get 1p, or just p.
3p + p
=4p
