  • 1 of 6: These doors are opened with a central control panel.
  • 2 of 6: This control panel is next to the entrance door.
  • 3 of 6: You would like to open cell door no 7.
  • 4 of 6: But when you set the lever to 7, another door opens.
  • 5 of 6: Everything is explained by the two equations on the control panel door.
  • 6 of 6: Solve this set of equations to find out in which position the lever has to be set to open cell door no 7.
