Question

Simplify the following expression:
4n - m + 3p + 2m - n - p

Answer 1

`= 3n + m + 2p` (first option)

Explanation:

`4n - m + 3p + 2m - n - p`

`4n - n = 4n - 1n = (4 - 1)n = 3n`

`3n - m + 3p + 2m - p`

`- m + 2 = - 1m + 2m = ( - 1 + 2)m = 1m = m`

`3n + m + 3p - p`

`3p - p = 3p - 1p = (3 - 1)p = 2p`

`= 3n + m + 2p`

Answer 2

The choose One

3n+m+2p
