A friend of Ms. Kiki L'mur, who is a geocacher, sent her a note: "I have a challenge for you. I have hidden a geocache at N40 57.abc W074 03.def. Can you find it? Use the following equations to solve for the missing numbers:
- 4a-7b+2c+d+3e-4f=-8
- a+b+c+d+e+f=39
- -3a+6b+2c-4d+e+5f=23
- a+3b-3c-2d+8e-3f=44
- 5a+4b+7c+3d-2e-f=116
- -2a+5b-c-4d+e+2f=1
Can YOU find the geocache? If you solve the puzzle and have no intention of finding the cache, write a note and comment on the puzzle itself!
Per the rules of geocaching, a Found It log must correspond to a signed logbook.
You can check your answers for this puzzle on GeoChecker.com.
BONUS: the cache container will have written in it a note with part of the coordinate for the puzzle series bonus cache, of the form LETTER=COORDINATE PIECE. Save these pieces of the bonus coordinate for use in geocache GC3T0ZY.
Happy caching!
Congratulations to Ragtime Fan and swampland'r for FTF!
