You can put this solution on YOUR website! What is this, a test or quiz??? Maybe just a homework assignment? You should do the ones that you can do first, and then ask us the ones that you had specific questions about. Anyway, most of these are just combining like terms. I'll do a couple of them for you. You do the rest!!
1. n+7 +y + 2 + z
Combine only the like terms, which in this case are the number terms: n+y + z + 9. You can write these in any order. We usually put them in alphabetical order with number terms last.
3. h+ 6 - (-4+h)
Use the distributive property to remove the parentheses:
h+6 +4 -h
Combine like terms (the h terms subtract out), and final answer is just 10.
6. -3(-2n-7y)
By distributive property, this is
6n + 21y
You do the rest!!
