Answer 7

usually you should start with the "more complicated" side and work (or simplify) to the side that's "less complicated".

then if you can't decide which side is more complicated, just pick any side and work your way to the other.

finally, if both sides seem equally complicated, work with one side and try to simplify as much as you can and do the same with the other side and work to the same place you ended with the other side.
