The simplest way is to use external mixer, but look forward to get one with
the inputs for low/high impedance (input for mic and line) for each
channel. Some simple mixers have only 1-2 low (mic) inputs and more high
inputs. The mic inputs on the mixer are 3 contacts/wires. The line inputs
are 2 or could be 3 - stereo. Here for example

You could however go the cheep way and play with multiple usb/pci audio
cards, jack and free audio software
If you want to experiment with linux and audio recording, you could look for
a supported multichannel audiocards and play with jack or audacity or some
other free software which will spare the external mixer.

My cheap and primitive way was to use two pc,s if you already have them, and
record two mono tracks, then use mixing software to align them and blend them.
There is plenty of such software available on debian and the quality is within the
guidelines of your mic quality, placement, echo/background noise.
I use headphones for the backing track and rarely use a second mic for guitar
then blend the two.  As I have been away from home and haven't done it for a 
while don't ask me for names of packages.
