Can't find equalizer in itunes

Check the Window menu. Next time, you can use the Help menu search that will show you directly where the item you want is.

 

If your looking for a function in one application, there is a help menu, which lets you search for items that might be there.
The screen shot by apfhex shows you this.
Press CMD+ALT/OPTION+2 to open the equalizer, or go to iTunes > Menu Bar > Windows > Equalizer

EDIT: something changed obviously while I wrote my post.

 

Yeah, added a screenshot to my post.

Something I want to touch on, and this isn't directed at the OP but in general, it's worth taking the time to learn how your computer functions and explore what options are available in programs instead of using excuses like "I'm new to Macs" or "computers are too complicated" like a lot of people do. I think once people get out of that mindset they can learn a lot.

Of course there are sometimes situations where an item can be placed in a bizarre spot. I know I've gone to the "View" menu enough times expecting something to be there, when it's in a totally different location (and the Help search doesn't... help, if you don't know exactly what the menu item is called).
