How to sync the songs from my laptop to my iphone?

So I just brought songs off itunes and need them on my phone. But I can't find the sync button anywhere!

Plug in yout iphone and open itunes. On the left side the name of your phone will show up. Click that an there should be a button that says sync.

I'm assuming you have the latest version of iTunes installed (version 11)? If so, follow these guides below

All you have to do is plug your iphone into the USB port and open up Itunes. Then find the songs you want to sync. You should be able to drag them over to your iphone. Click and hold the song title and a little pop up show show up in the upper right hand corner. Drag it to where it says (your name's) Iphone or ipod. It is then automatically synced. Hope this helps.
