$= > 5m - 7n + 3n - 4m + 2 + 2m - 3mn - 5$

=>Arrange like terms together to make our calculation easier:

$= > 5m - 4m + 2m - 7n + 3n - 3mn + 2 - 5$

$= > m + 2m - 4n - 3mn + 2- 5$

$= > 3m - 4n - 3mn - 3$

=>Here,3 comes three times with three different terms so ,we take 3 as a common.

$= > 3m - 3mn - 3 - 4n$

$\bold{\red{ = > 3(m - mn - 1) - 4n}}$
