Answer 1

Aduni toate relațiile și obții
a+a+b+b+c+c=32754+27864+35564
2(a+b+c)=96182⇒a+b+c=48091.
Dar a+b=32754
Din ultimele două ⇒c=48091-32754⇒c=15337.
a+c=35564⇒a=35564-c=35564-15337⇒a=20227.
a+b=32754⇒b=32754-a⇒b=32754-20227⇒b=12527.

Answer 2

$\displaystyle a+b=32754 \\ b+c=27864 \\ a+c=35564 \\ a+b+b+c+a+c=32754+27864+35564 \Rightarrow 2a+2b+2c=96182 \\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \Rightarrow 2(a+b+c)=96182 \Rightarrow a+b+c= \frac{96182}{2} \Rightarrow \\ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ \Rightarrow \boxed{a+b+c=48091} \\ 32754+c=48091 \Rightarrow c=48091-32754 \Rightarrow \boxed{c=15337} \\ b+15337=27864 \Rightarrow b=27864-15337 \Rightarrow \boxed{b=12527}$
$a+12527=32754\Rightarrow a=32754-12527 \Rightarrow \boxed{a=20227} \\ Verificare : 20227+12527+15337=\boxed{48091}$
