\[(x + 3y - 2)^{2} + (x - 5y)^{2} = 0\]
\[\left\{ \begin{matrix} x + 3y = 2 \\ x - 5y = 0 \\ \end{matrix} - \right.\ \text{\ \ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} 8y = 2\ \ \ \ \ \ \ \ \\ x = 2 - 3y \\ \end{matrix} \right.\ \text{\ \ \ \ \ \ \ \ \ \ }\]
\[\left\{ \begin{matrix} y = \frac{1}{4} \\ x = \frac{5}{4} \\ \end{matrix} \right.\ \]
\[Ответ:\left( 1\frac{1}{4};\frac{1}{4} \right).\]
