To subtract the expressions \((-5a + 8)\) and \((-4a - 7)\), you can rewrite the expression like this:

\[
(-5a + 8) - (-4a - 7)
\]

Next, distribute the negative sign across the second expression:

\[
-5a + 8 + 4a + 7
\]

Now, combine like terms:

1. Combine the \(a\) terms: \(-5a + 4a = -a\)
2. Combine the constant terms: \(8 + 7 = 15\)

Putting it all together, the expression simplifies to:

\[
-a + 15
\]

So, the final result is:

\[
-a + 15
\]
