Tex Murphy: Overseer Hints

I'm terrible in math, please help me.

  • 1 of 7: Let's start with what we have: e+o=2 and o-e=8.
  • 2 of 7: Rewriting these equations gives us: e=2-o and e=o-8.
  • 3 of 7: So 2-o=o-8 or 2o=10 or o=5.
  • 4 of 7: As a result e=2-o or e=2-5=-3.
  • 5 of 7: These values for o and e are the correction factors to be used on the door mechanism.
  • 6 of 7: If you set the lever to an odd number (e.g. 3) then that cell door +5 will open (in this case door no 8), if you set the lever to an even number (e.g. 8) then that cell door -3 will open (in this case door no 5).
  • 7 of 7: Now, to open cell door no 7, you have to put the lever at 10 (10-3=7).
