\[\boxed{\mathbf{10.}}\]

\[\textbf{а)}\ 5x + 6x = 2211\]

\[11x = 2211\]

\[x = 2211\ :11\]

\[x = 201.\]

\[Ответ:201.\]

\[\textbf{б)}\ 23x + x - 10 = 38\]

\[24x = 38 + 10\]

\[24x = 48\]

\[x = 48\ :24\]

\[x = 2.\]

\[Ответ:2.\]

\[\textbf{в)}\ 1457\ :(7 + 8x) = 47\]

\[7 + 8x = 1457\ :47\]

\[8x + 7 = 31\]

\[8x = 31 - 7\]

\[8x = 24\]

\[x = 24\ :8\]

\[x = 3.\ \]

\[Ответ:\ 3.\]

\[\textbf{г)}\ 15x - 2x + 14x = 2916\]

\[27x = 2916\]

\[x = 2916\ :27\]

\[x = 108.\]

\[Ответ:108.\]
