Distribute Negative Sign: We have the expression (9w+9)−(4w+2). First, distribute the negative sign across the terms in the second parentheses.(9w+9)−(4w+2) becomes 9w+9−4w−2.
Combine Like Terms: Combine like terms by subtracting 4w from 9w and −2 from 9. 9w−4w gives 5w, and 9−2 gives 7. So, the expression simplifies to 5w+7.
Check for Errors: Check for any mathematical errors in the previous steps. We distributed the negative sign correctly and combined like terms without any mistakes.
