To simplify the expression \((3x + 4) - (-x - 5)\), start by distributing the negative sign across the second term:
\[
(3x + 4) + (x + 5)
\]
Next, combine like terms:
1. Combine the \(x\) terms: \(3x + x = 4x\)
2. Combine the constant terms: \(4 + 5 = 9\)
Putting it all together, we get:
\[
4x + 9
\]
So, the simplified expression is:
\[
\boxed{4x + 9}
\]
\[
(3x + 4) + (x + 5)
\]
Next, combine like terms:
1. Combine the \(x\) terms: \(3x + x = 4x\)
2. Combine the constant terms: \(4 + 5 = 9\)
Putting it all together, we get:
\[
4x + 9
\]
So, the simplified expression is:
\[
\boxed{4x + 9}
\]
