Help, please, in words of few sylables........
As other have said, there are much easier ways to install software under linux these days, but to answer your original question.
When you unpacked the .tar file what did it create? I'd expect it to create a folder which includes a fairly obvious installer programme.
You should just need to run that programme by clicking on it from the file manager. You may need run it as the 'root' user?
Oh, and make sure you cross your fingers as you do it.
