Question

suma a trei numere este 16.Daca din fiecare numar se cade acelasi numar ,se obtin numerele 3,5 4,2 si 5,3.Aflati cele trei numere.

Answer 1

a+b+c=16
a-x=3.5 ->a=3.5+x
b-x=4.2 ->b=4.2+x
c-x=5.3 ->c=5.3+x
3.5+x+4.2+x+5.3+x=16
3x+13=16 -> 3x=3 -> x=1 si
a-1=3.5 -> a=4.5
b-1=4.2 -> b=5.2
c-1=5.3 -> c =6.3

Answer 2

a+b+c=16
a-x=3,5
b-x=4,2
c-x=5,3


3,5+x+4,2+x+5,3+x=16
3x=16-13
x=1
a-1=3,5 =>a=4,5
b-1=4,2=>b=5,2
c-1=5,3=>c=6,3
