\rm{
notam  m= varsta mamei;  t=varsta tatalui  si  d=varsta lui Darius ;\\
stiim ca \{m+t=67 (ani)\\
m=3\cdot {d} si\\
t=m+4 =3d+4
\rm{ \Rightarrow  m+t=67 \Leftrightarrow  3d + 3d+4 = 67 de unde se obtine 6d=63 ... d=63:6 = ...

\rm{ Cred ca m+t \ne 67 (ani)  Exclamation
\rm{ Este posibil ca m+t=64 (ani)  Question
