Решите систему уравнений: 5x-y=2; 4x+2y=8.

\[\left\{ \begin{matrix} x = \frac{6}{7}\text{\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ } \\ y = \frac{5\ \cdot 6}{7} - 2 = \frac{30}{7} - 2\ \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ }\]

\[\left\{ \begin{matrix} x = \frac{6}{7}\text{\ \ } \\ y = \frac{16}{7} \\ \end{matrix} \right.\ \]

\[Ответ:\left( \frac{6}{7};\frac{16}{7} \right).\]
