Chemistry.... why is it so.... ARGH!

I know I shouldn't be posting, but I need to vent. I have been working on Chemistry for about 20 hours now, (since my last post) and I am very frustrated. I just DON'T get it. It's so frustrating. And then they throw in all these complex log things that I cannot figure out. 4.40=4.266+log (x/0.03754-x). How the heck do you figure out x. The text tells us nothing about logs, but uses them nearly every page. I have been trying to figure out this one for a while. A math major friend of mine attempted to help me, but it wasn't going so well. Apparently he hasn't done much logs since highschool. :( Chemistry is an awful subject. I just want to pass, but it's making things difficult.
