Question

suma a 3 numere naturale este 3081. daca din fiecare se scade acelasi numar,se obtin numerele:1010,1020,1030. calculati numerele initiale

Answer 1

a+b+c=3081
a-x=1010⇒a=1010+x
b-x=1020⇒b=1020+x
c-x=1030⇒c=1030+x
1010+x+1020+x+1030+x=3081
3060+3x=3081
x=(3081-3060)/3
x=21/3
x=7
a=1010+7
a=1017
b=1020+7
b=1027
c=1030+7
c=1037
1017+1027+1037=3081
