\[\boxed{\mathbf{517\ (517)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ (2 + 2)\ :(2 + 2) = 1\]

\[2)\ 2\ :2 + 2\ :2 = 2\]

\[3)\ (2 + 2 + 2)\ :2 = 3\]

\[4)\ 2 + 2 + 2 - 2 = 4\]

\[5)\ 2 + 2 + 2\ :2 = 5\]

\[6)\ (2\ :2 + 2) \cdot 2 = 6\]

\[7)\ 2 + 2 + 2 + 2 = 8\]

\[8)\ 2 \cdot 2 \cdot 2 + 2 = 10\]

\[\boxed{\ \mathbf{517\ (457)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ 13x = 195\]

\[x = 195\ :13\]

\[x = 15.\]

\[Ответ:15.\]

\[2)\ x \cdot 18 = 468\]

\[x = 468\ :18\]

\[x = 26.\]

\[Ответ:26.\]

\[3)\ 11x + 6x = 408\]

\[17x = 408\]

\[x = 408\ :17\]

\[x = 24.\]

\[Ответ:24.\]

\[4)\ 33m - m = 1024\]

\[32m = 1024\]

\[m = 1024\ :32\]

\[m = 32.\]

\[Ответ:32.\]

\[5)\ x\ :19 = 26\]

\[x = 26 \cdot 19\]

\[x = 494.\]

\[Ответ:494.\]

\[6)\ 476\ :x = 14\]

\[x = 476\ :14\]

\[x = 34.\]

\[Ответ:34.\]
