Ugly graph but yeah, general idea is to
1) solve for both equation individually so you know where their points would lie.
2) set up your axis range base on what you solved in 1)
3) draw nicer than what I drew
4) estimate de points where the 2 graphs cuts
5) solution will be the x-coordinates of the points in 4)
