Question

Suma a trei numere este 975. Daca din fiecare numar se scade acelasi numar se obtin numerele 12,345 si 126.Care sunt cele trei numere?

Answer 1

a+b+c=975
x-nr. scazut
a-x=12⇒a=x+12
b-x=345⇒b=x+345
c-x=126⇒c=x+126
x+12+x+345+x+126=975⇒3x+483=975⇒3x=⇒492⇒x=164⇒
a=176 , b=509 , c=290

Answer 2

a+b+c= 927
a-x=12=> a=x+12
b-x=345=> b=x+345
c-x=126=>c=x+126

x+12+x+345+x+126=3x+483=> x= 483:3=> x=161

a=161+12
a=173

b=161+345
b=506

c=161+126
c=287
