Question

tkhunny · Answer

It's EXACTLY like the other one.

-21
-21 + a
-21 + 2a
-21 + 3a
-21 + 4a
-21 + 5a = -36

Why would it be any different?

I'm homeschooled and don't have much help

You MUST get adequate help with the Mathematics.  Hire a tutor.  Something.  Whoever is supervising your education, maybe a parent or guardian, needs to come to terms with this.

anonymous · Answer

Being homeschooled has nothing to do with the curriculum. You would have chosen a curicullum and then you would still have sufficient amount of information to learn from.
