Answer: 3x + 6
Explanation:
To simplify the expression (x + 1) - (-2x - 5), we can follow these steps:
1. Distribute the negative sign inside the parentheses: (x + 1) + (2x + 5).
2. Remove the parentheses and combine like terms: x + 1 + 2x + 5.
3. Combine like terms: (x + 2x) + (1 + 5).
4. Simplify: 3x + 6.
Therefore, the simplified expression is 3x + 6.
