Question

5m + 3n + p, -5p + 3n, and 2n - m. its been a while since ive tried this stuff and my son needs help

Answer 1

um is this simplifying ? if so all u have to do is collect like terms :3

Answer 2

what is it you are trying to accomplish?

Answer 3

5m + 3n + p - 5p + 3n + 2n -m
Rearrange them
5m - m + 3n + 3n + 2n +p -5p
= 4m +8n -4p
= 4(m+2n-p)

Answer 4

5m + 2n = 3
-5m +3n = 7
--------------------
5n = 10
n = 10/5
n = 2

substitute the value of n in equation 1
5m + 2n = 3
5m + 2(2) = 3
5m + 4 = 3
5m = 3 - 4
5m = -1
m = -1/5

hence, n = 2 and m = -1/5

Answer 5

Thanks guys and yes I was trying to simplify but its been quite a while
