Решите систему уравнений: 3x-2y=5; 11x+3y=39.

\[\left\{ \begin{matrix} 3x - 2y = 5\ \ \ \ \ \ \ \ | \cdot 3 \\ 11x + 3y = 39\ \ \ | \cdot 2 \\ \end{matrix} \right.\ \]

\[\left\{ \begin{matrix} 9x - 6y = 15\ \ \ \\ 22x + 6y = 78 \\ \end{matrix} \right.\ ( + )\]

\[31x = 93\]

\[x = 3.\]

\[2y = 3x - 5 = 9 - 5 = 4\]

\[y = 2.\]

\[Ответ:(3;2).\]
