-
Combine like terms: Identify and combine the d terms and the constant terms:
6d + 3d + 5 - 2 = 9d + 3
Final Result
Therefore, the simplified form of (6d + 5) - (2 - 3d) is 9d + 3.
Key Points to Remember
- Distribute the negative sign when subtracting expressions in parentheses.
- Combine like terms to simplify the expression.
