Answer 3

Let's simplify the expression step by step:

1. Distribute the negative sign inside the parentheses: -4(-5m - 4n) - 6 - (-4m - 3n)

   becomes:

   20m + 16n - 6 + 4m + 3n

2. Combine like terms (terms with the same variables): (20m + 4m) + (16n + 3n) - 6

   becomes:

   24m + 19n - 6

So, the simplified expression is: $24m + 19n - 6$
