To simplify the expression \(-3a + 4 + 5a - 7 + a\), we can combine like terms.
1. Combine the \(a\) terms:
\(-3a + 5a + a = (5a - 3a + 1a) = 3a\)
2. Combine the constant terms:
\(4 - 7 = -3\)
Now, putting it all together, we have:
\[
3a - 3
\]
Therefore, the expression \(-3a + 4 + 5a - 7 + a\) is equivalent to the option:
**B. 3a - 3**
