Explicación paso a paso:

$3m-\left(5m+n-\left(5m-n\right)\right)-\left(3m-2n\right)$

------------------------------------------------------

• $5m+n-\left(5m-n\right)$

$=5m+n-5m+n\\=2n$

• $-\left(3m-2n\right)$

$=-\left(3m\right)-\left(-2n\right)\\=-3m+2n$

------------------------------------------------------

$=3m-2n-3m+2n\\=3m-3m-2n+2n\\=-2n+2n\\=0$
