  Got! The paper asked me to do 8x8 simulataneous equations...
  
  but hinted that this can be downsized to 4x4 once you figured out the trick

  A Maths got teach.
  
  Can't remember it though. Use matrix to solve. But will die doing it. 2x2 already take up one page of foolscap paper.

  Yeah matrix algebra.. or some matrix manipulation..
  
  Like what 798 said .. everything you and I learn in Singapore's "Wolrd Crass University" return back to lecturer once you go out
