Question

suma a trei numere naturale este7050.Daca din fiecare se scade acelasi nr.se obtin numerele 3600 ,1600, 1400.afla numerele initiale.

Answer 1

a+b+c=7050
a-x=3600⇒a=3600+x
b-x=1600⇒b=1600+x
c-x=1400⇒c=1400+x
3600+x+1600+x+1400+x=7050
3x=7050-3600-1600-1400
3x=450
x=150
a=3600+150=3750
b=1600+150=1750
c=1400+150=1550

Answer 2

a+b+c=7050
a-x=3600
a=3600+x

b-x=1600
b=1600+x

c-x=1400
c=1400+x

3600+x+1600+x+1400+x=7050
6600+3x=7050
3x=7050-6600
3x=450
x=150

a=150+3600=3750
b=150+1600=1750
c=150+1400=1550
