To add the polynomials \((x + 5)\) and \((4x - 7)\), you can combine like terms.
1. **Identify like terms:**
- The like terms for \(x\) are \(x\) and \(4x\).
- The constant terms are \(5\) and \(-7\).
2. **Combine like terms:**
- For the \(x\) terms: \(x + 4x = 5x\)
- For the constant terms: \(5 - 7 = -2\)
3. **Write the result:**
- Combine the results of the like terms:
\[
5x - 2
\]
So, \((x + 5) + (4x - 7) = 5x - 2\).
