Answer 3

\[
\left\{\left\{x\to -2 \sqrt{\frac{58}{65}},
y\to -3
\sqrt{\frac{7}{65}}\right\},
\\
\left\{x\to -2
\sqrt{\frac{58}{65}},y\to 3
\sqrt{\frac{7}{65}}\right\},
\\
\left\{x\to 2
\sqrt{\frac{58}{65}},y\to -3
\sqrt{\frac{7}{65}}\right\},
\\
\left\{x\to 2
\sqrt{\frac{58}{65}},y\to 3
\sqrt{\frac{7}{65}}\right\}\right\}
