I have a logical puzzle here that I need to solve. I'm not after just the answer of this puzzle, but also the reasoning and thought-process behind solving it. Any assistance is greatly appreciated.
What number between 1 and 7 do the following equal? A=, B=, C=, D=, E=, F=, G=
1. A ≠ 2 2. A + B = F 3. C – D = G 4. D + E = 2F 5. E + G = F
The rules are:
1. All the variables (A, B, C, D, E, F, G) are equal to integer values between 1 and 7 2. None of the variables (A, B, C, D, E, F, G) are equal to each other i.e. all seven values will be used, no repeat use of integers
