Question

Ma puteti ajuta?Dau coroana

Answer 1

a+b+c=3726

a+b=2159

b+c=2200

b=2159-a (1)

(2159-a)+c=2200

-a+c=2200-2159

-a+c=41 =>c=41+a (2)

a+2159-a+41+a=3726

a=3726-2200=>a=1526(lei primul copil)

(1)=>b=633(lei al doilea copil)

(2)=>c=1567(lei al treilea copil)

Verificare: a+b+c=1526+633+1567=3726
