Answer 2

To simplify the expression $-(5n+m)+(-4n+8m)-(2m-5n)$, we can combine like terms.

Let's break it down step by step:

1. $-(5n+m)+(-4n+8m)-(2m-5n)$
2. $-5n - m - 4n + 8m - 2m + 5n$
3. $(-5n - 4n + 5n) + (8m - 2m) - m$
4. $-4n + 6m - m$
5. $-4n + 5m$

So, the simplified form of the expression is $-4n + 5m$.
