Hey every1 I have some questions here that I need an easier way to graph with.

1. | x+y | + | y | + | x-y | = 12 Do I really have to consider all 6 cases here!!

2. | x+y | + | x-y | + | x | + | y | = 12 Like seriously... how many cases do you even need to consider here..

Might as well lol. Some of the cases basically cancel out anyways
