Oh alright, the book was very unclear about a problem like that. I thought that the 8x-10 cancelled and became 1. Oops.
And I didn't get that you meant 8/2.
But hrm. I do get what I did wrong now.
You guys are incredibly helpful here. I won't post anymore problems that I have until it is determined whether what I am asking for is illegal.
EDIT: The WebCT exercise I was given was a homework exercise, it does have to be turned in by a certain time, however we are allowed to ask for outside assistance (or so it says in the syllabus) I do get course marks for it. I'm very sorry if this was not allowed. It is specifically not a quiz, however (one could post quizzes on there, but also regular HW assignments like this one)
No, to my knowledge I am perfectly allowed to seek out assistance from people. There's even a math lab at the school that I can go to for my homework and ask questions like I am here. Unfortunately it is closed on the weekends.
Yes, it is part of my course assessment, however.
