\[\boxed{\text{874\ (874).\ }\text{Еуроки\ -\ ДЗ\ без\ мороки}}\]
\[1)\ y = 3,7x + 10\ \ и\ \]
\[\ y = 1,4x - 13\]
\[3,7x + 10 = 1,4x - 13\]
\[2,3x = - 23\]
\[x = - 10\]
\[y = 3,7 \cdot ( - 10) + 10 =\]
\[= - 37 + 10 = - 27\]
\[Ответ:( - 10;\ - 27).\]
\[2)\ y = 4 - \frac{2}{7}\text{x\ \ }и\ \ y = \frac{9}{7}x + 26\]
\[4 - \frac{2}{7}x = \frac{9}{7}x + 26\]
\[- \frac{11}{7}x = 22\]
\[x = \frac{- 22 \cdot 7}{11} = - 14\]
\[y = 4 - \frac{2}{7} \cdot ( - 14) = 4 + 4 = 8\]
\[Ответ:( - 14;8).\]
