Corfu Conundrum Mystery Cache

The cache is not at the above location but can be found within a couple of Kilometres of here.

To find the cache you'll need to solve the fifteen simple sums below. Each letter A to Z represents a number from 1 to 26 - all you need to do is work out which number corresponds to which letter.

Hint: the value for the letter Z can be determined by elimination.

A + B = D
B * K = C
F * U = D
F * K = L
H + I = J
Q * Q = R
R + S = T
T = K * G
U + V = W
F + K = Q
W + H = O
D + E = N + P
V * W = X + Y
O + V = N
M + I = Y

The cache is located at:

North # ## . ### where # = (H*L)-B, ## = L*U, ### = (V*X*M)+P

East # ## . ### where # = (D-Y)+J, ## = (U*U)-K, ### = (R*R)+(W*H)

You can check your answers for this puzzle on Geochecker.com (Don't forget to change W to E).
