Need help with an equation

Hey there i need to find out;
(C/A)-(D(F+E)(B-H)/E)=X
X+D=Y
Y²+A=J

C-(D*A)²+3(G+E)=X
G(B+H)+(F²*E+I)=Y
X-Y=K

When A=5 B=30 C=1965 D=7 E=2 F=4 G=7 H=12 I=1
Please help, its not homework, its to work out a set of co-ordinates for the GPS sport www.geocaching.com, which is basically treasure hunting.
:eek2:
Thanks for the help!

So, the unknowns are J,K,X and Y?

Yes, but the two sets of x+ys are different- hence the 2 equations for one letter.

If these are 2 sets of 3 equations the solution is almost trivial, just substitute the given values of the parameters A, B, C,... What's exactly what you don't know how to do?
