Answer: -15p + 41q
Step-by-step explanation:
Problem: -9(4p-6q) + 8q- 7(3q - 3p)
1. Expand by distributing terms
−(36p−54q) + 8q − 7(3q − 3p)
2. Expand by distributing terms
−(36p−54q) + 8q − (21q − 21p)
3. Remove parenthesis
−36p + 54q + 8q − 21q + 21p
4. Collect like terms
(−36p + 21p) + (54q + 8q − 21q)
5. Simplify
-15p + 41q
