Lecture, where we covered mesh analysis, and did some examples. You pretty much state mesh currents within loops, and then follow them around multiplying by the resistances (due to Ohm's Law); currents going in opposite directions are subtracted with your current mesh current going first. The whole idea is based off of KVL that the sum of voltages in a loop is = 0.
