Question

Diferenta a 2 numere este 38,45.Daca se imparte primul la al doilea,obtinem catul 3,5 si restul 2. Aflati numerele.

Answer 1

a,b-nr.
a-b=38,45
a:b=3,5 rest 2
a=b×3,5+2
a=3,5b+2
3,5b+2-b=38,45
3,5b-b=38,45-2
2,5b=36,45
b=36,45:2,5
b=14,58
a=3,5b+2
a=3,5×14,58+2
a=53,03

Answer 2

a+b =38.45
a/b =3.5  r  2  ;    a =3.5b +2

3.5b+2 - b =38.45
2.5b =38.45-2 =36.45
b =14.58

a =3.5b+2
a =3.5*14.58 +2 =51.03+2 =53.03
v ;   53.03 -14.58 =38.45
