Hi Luis,
Thanks for your breakdown of the expression! You've done a great job organizing the terms. Just to reiterate your final expression for clarity:
The original expression: 6xy − 2y + x + y − 99
After grouping and simplifying:
- The term with \( xy \) is \( 6xy \).
- The combined \( y \) terms are \( -2y + y = -y \).
- The \( x \) term remains \( x \).
- The constant is \( -99 \).
So the final simplified expression is: 6xy + x - y - 99
If there's anything else you'd like to discuss or if you have further questions, feel free to ask!
Best, [Your Name]
