\[\boxed{\mathbf{1415}\mathbf{\ (1001)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ 8 \cdot (x - 1,4) = 0,56\]

\[x - 1,4 = 0,56\ :8\]

\[x = 0,07 + 1,4\]

\[x = 1,47\]

\[Ответ:1,47.\]

\(2)\ (4,6 - x) \cdot 19 = 4,18\)

\[4,6 - x = 4,18\ :1,9\]

\[x = 4,6 - 2,2\]

\[x = 2,4\]

\[Ответ:2,4.\]

\(3)\ (51,32 + x) \cdot 0,12 = 72\)

\[51,32 + x = 72\ :0,12\]

\[x = 600 - 51,32\]

\[x = 548,68\]

\[Ответ:548,68.\]

\(4)\ 17,28\ :(56 - x) = 36\)

\[56 - x = 17,28\ :36\]

\[x = 58 - 0,48\]

\[x = 55,52\]

\[Ответ:55,52.\]
