I cannot figure out how to do this problem. The way they show you how to do it on my online math homework software is in a very complicated and drawn out longhand way. I am pretty convinced there is a way to do this on my TI-84 calculator since that is what I have been able to do for all my other problems. So I would greatly appreciate it if someone could show me how.
