# help: algebra question?

How to find I, J, K, L from

A = N * ( I - 1) + K

B = N * ( J - 1) + L

for a given A, B and N?

Thank you in advance.

Update:

The range of I, J, K, L is 1 to N and the range of A, B is 1 to N^2.

If A, B and N are given, why don't you give them to me so I can work with them!?!?!?

I = (N-K+A)/N

J = (N-L+B)/N
