a b c d with a and c even
a = 2 d ( so a is even all right :)
a + b = 11
b+ c = 9
c + d = 7
====================
2d + b = 11
b - d = 2
-------------------subtract
3 d = 9
d = 3 whew, odd
now go back
a = 2 d ( so a is even all right :)
a + b = 11
b+ c = 9
c + d = 7
====================
2d + b = 11
b - d = 2
-------------------subtract
3 d = 9
d = 3 whew, odd
now go back
