Question

Suma a 3 numere naturale este 7050.Daca din fiecare se scade acelasi numar de obtin numerele 3600, 1600 si 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​

(3600+1600+1400)+3×x=7050​

6600+3×x=7050​

3×x=7050−6600​

3×x=450​

x=450÷3​

x=150​​

a=150+3600=3750​

b=150+1600=1750​

c=150+1400=1550​​
