Answer 1

To solve the equation \(-3a + 5 + 4a = 8 - 28\), let's simplify both sides step by step.

1. **Simplify the right side:**
\[
8 - 28 = -20
\]

2. **Rewrite the equation:**
\[
-3a + 5 + 4a = -20
\]

3. **Combine like terms on the left side:**
\[
(-3a + 4a) + 5 = -20
\]
\[
1a + 5 = -20
\]
\[
a + 5 = -20
\]

4. **Isolate the variable \(a\) by subtracting 5 from both sides:**
\[
a = -20 - 5
\]
\[
a = -25
\]

So, the solution to the equation is:
\[
\boxed{-25}
\]

Therefore, the correct answer is **B. negative 25**.
