\[\boxed{\mathbf{1126\ (1118)}\mathbf{.}\mathbf{\ }Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ 9x = - 54\]

\[x = - 54\ :9\]

\[x = - 6\]

\[Ответ:\ - 6.\]

\[2)\ 1,2x = - 6\]

\[x = - 6\ :1,2\]

\[x = - 5\]

\[Ответ:\ - 5.\]

\[3)\ 13x = - 6\]

\[x = - 6\ :13\]

\[x = - \frac{6}{13}\]

\[Ответ:\ - \frac{6}{13}.\]

\[4) - 21x = 48\]

\[x = 48\ :( - 21) = - \frac{48}{21}\]

\[x = - \frac{16}{7} = - 2\frac{2}{7}\]

\[Ответ:\ - 2\frac{2}{7}.\]

\[5)\ 2\frac{1}{7}x = - 1\frac{11}{14}\]

\[x = - \frac{5}{6}\]

\[Ответ:\ - \frac{5}{6}.\]

\[6) - 3,78\ :x = - 0,6\]

\[x = - 3,78\ :( - 0,6)\]

\[x = 6,3\]

\[Ответ:6,3.\]

\[7)\ x\ :\left( - 1\frac{3}{13} \right) = - 0,26\]

\[x = \frac{8}{25} = 0,32\]

\[Ответ:0,32.\]

\[8)\ 18\ :( - x) = 0,6\]

\[- x = 18\ :0,6 = 30\]

\[x = - 30\]

\[Ответ:\ - 30.\]
