In the below diagram are nine triangles lettered A through I. Each letter has a number value of 1 through 9 and no two triangles have the same number. The numbers in the circles are the sum of the triangles touching that circle. For example, triangles A, B & C touch the circle containing the number 18. Therefore A+B+C=18. Once you solve the numbers for each triangle you can then solve for the final coordinates with a little addition and subtraction.
A preform is hidden at these final coordinates:
N 42° 49.[X] [X] [X]
W 86° 01. [Y] [Y] [Y]
[X] [X] [X] = [F+B-E] [B+G] [H+A]
[Y] [Y] [Y] = [D+G-H] [C-E] [I-A]
