\left \{ {{4x+3y=36|\cdot 2} \atop {5x+6y=50}} \right. \Leftrightarrow \left \{ {{8x+6y=72} \atop {5x+6y=50}} \right. \\
\text{Daca scadem relatiile:} 3x/=22\Rightarrow \boxed{x=\dfrac{22}{3}\ lei}(\text{pretul unei lalele})\\
\dfrac{88}{3}+3y=36\\
3y=36-\dfrac{88}{3}\\
3y=\dfrac{20}{3}\Rightarrow \boxed{y=\dfrac{20}{9}\ lei}(\text{pretul unei frezie})
