\[\boxed{\text{1070\ (1070).}\text{\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
\[Ответ:(0,05;0,5).\]
\[105x + 105y = 0\]
\[105 \cdot (x + y) = 0\]
\[x = - y\]
\[- 33y + 69y + 14y^{2} + 4y^{2} = 0\]
\[18y^{2} + 36y = 0\]
\[18y \cdot (y + 2) = 0\]
\[y \neq 0,\ \ y = - 2\]
\[x = - y,\ \ x = 2\]
\[Ответ:(2;\ - 2)\text{.\ }\]
