a+b=26.193
b+c=708.585

Answer 1

a=721326-708585=12741
c=721326-26193=695133
b=721326-12741-695133=24919

Answer 2

$\displaystyle a+b+c=721326 \\ a+b=26193 \\ b+c=708585 \\ 26193+c=721326 \Rightarrow c=721326-26193 \Rightarrow \boxed{c=695133} \\ b+695133=708585 \Rightarrow b=708585-695133 \Rightarrow \boxed{b=13452} \\ a+13452=26193 \Rightarrow a=26193-13452 \Rightarrow \boxed{a=12741} \\ Verificare:12741+13452+695133=\boxed{721326}$
