Question

Determinati 3 nr. daca suma lor este 1090,suma primelor 2 este 837 si suma ultimelor 2 este 730

Answer 1

a+b+c=1090
a+b=837
b+c=730
a=837-b
c=730-b
837-b+b+730-b=1090
837-2b+730-b=1090
837-b=1090-730
837-b=360
b=837-360
b=477
a=837-477
a=360
c=730-477
c=253
Rezultate;a=360;b=477;c=253.

Answer 2

a+b+c=1090
a+b=837
b+c=730
837+c=1090
c=1090-837
c=253
a+730=1090
a=1090-730
a=360
360+253=613
1090-613=477
b=477
360+477+253=1090
