Hello all,
could someone help using excel to calculate the unknow A, B, C.
0.25 A = B + C
3.6 B = A + C
8.5 C = A + B
Thank you very much for your help!

Without constants, the solution is always A = 0, B = 0, C = 0. At least by normal problem solving methods (matrix manipulation,
substitutions, etc...)

You need something like
0.25A - B - C = 10
-A + 3.6B - C = 5
-A - B - 8.5C = 2
Then you can get values for A, B and C
