kiwi, post these on the original question, so we don't have to go back and forth. It is confusing.
6(a+3b)- 4(2b-5a)
You missed the sign on 20a. Notice you have a -4 times -5a. That give a POSITIVE 20a
6a + 18b - 8b- 20a
is the answer 26a + 10b

Kiwi, your answer is right, 26a+10b. I did it in a hurry. Sorry. Please followup on the same post, not new ones.
