Answer 1

To simplify the expression \(-8(x - 3y) + 5(-2x - 7y)\), we can follow the steps below:

1. **Distribute \(-8\) in the first term:**
\[
-8(x - 3y) = -8 \cdot x + (-8) \cdot (-3y) = -8x + 24y
\]

2. **Distribute \(5\) in the second term:**
\[
5(-2x - 7y) = 5 \cdot (-2x) + 5 \cdot (-7y) = -10x - 35y
\]

3. **Combine the two results:**
\[
-8x + 24y - 10x - 35y
\]

4. **Combine like terms for \(x\) values:**
\[
-8x - 10x = -18x
\]

5. **Combine like terms for \(y\) values:**
\[
24y - 35y = -11y
\]

6. **Put the results together:**
\[
-18x - 11y
\]

So, the simplified expression is:
\[
\boxed{-18x - 11y}
\]
