1) Nickolas, if you increase 6 by 2 what do you get?
2) How did you get that?
3) So if you increase x by 2 what do you get?
Please answer those 3 questions for me here. on this thread.
I think this thread is a bit old so after you have done it can you please message me with the address of the question so I can come and have a look at what you have done. (Otherwise I might not see your answer)
