This is the way algebra should be taught in school. So many people, including myself struggle, to see how algebra applies to real world situations. This was difficult but helpful. In problem 2 you did what I did. Plugged the 3 in for y in the more complex equation. After figuring out x that way I realized it was way simpler to plug 3 into the x+y=5 to get 2 for x.
