a+b+c=2766
a=14+2b
c=(a+b)/2 =>a+b=2c
Inlocuim in prima expresie si avem 2c+c=2766 sau 3c=2766 =>c=922
a+b=2x922
a+b=1844 lx2
a-2b=14
2a+2b=3688
a - 2b= 14
___________ ''+''
3a / =3702 =>a=1234 =>b=1844-1234 =>b=610
d:e=4 rest 379 =>d=4e+379
d+e=2629
4e+379+e=2629
5e=2629-379
5e=2250 =>e=450 =>d=2629-450 =>d=2179
