\[\left\{ \begin{matrix} 2x - 5y + 33 = 0\ \ | \cdot 3 \\ 3x - 8y + 52 = 0\ | \cdot 2 \\ \end{matrix} \right.\ \text{\ \ \ \ \ }\]
\[\left\{ \begin{matrix} 6x - 15y + 99 = 0\ \ \\ 6x - 16y + 104 = 0 \\ \end{matrix} \right.\ \ \ ( - )\ \ \]
\[\ \left\{ \begin{matrix} y = 5\ \ \ \ \ \ \ \ \ \ \ \ \ \ \\ x = \frac{5y - 33}{2} \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} y = 5\ \ \ \ \\ x = - 4 \\ \end{matrix} \right.\ \]
\[Ответ:( - 4;5).\]
