Hi
Book answer: -p + 10q and Your answer: 10q + -p say the same thing.
Note: as would: 9q + 6p - 7p + q = 10q - p
the important thing is that 'Like terms' are being combined for simplification.

Your answer is correct technically BUT
1. It's not correct to write two symbols together like + -. It would simplify to just -.
2. Normally the answer is written with letters in alphabetical order. So p comes BEFORE q, that's why the answer should be -p+10q.
:)
