Let's simplify the expression step by step:

\[
-4(-8w - 4x) - 7x - 10(-10x + 8w)
\]

### Step 1: Distribute the terms inside the parentheses
- For the first term, distribute \(-4\) to both \(-8w\) and \(-4x\):
\[
-4(-8w) = 32w, \quad -4(-4x) = 16x
\]
- For the second term, distribute \(-10\) to both \(-10x\) and \(8w\):
\[
-10(-10x) = 100x, \quad -10(8w) = -80w
\]

Now, the expression becomes:
\[
32w + 16x - 7x + 100x - 80w
\]

### Step 2: Combine like terms
- Combine the \(w\)-terms:
\[
32w - 80w = -48w
\]
- Combine the \(x\)-terms:
\[
16x - 7x + 100x = 109x
\]

### Final Expression:
\[
-48w + 109x
\]

So, the simplified expression is:

\[
-48w + 109x
\]
