\[\boxed{\mathbf{755\ (755)}.\ Еуроки\ - \ ДЗ\ без\ мороки}\]

\[1)\ 972 - 912 = 60\ :5 =\]

\[= 12 + 19 = 31 \cdot 5 =\]

\[= 155 - 47 = 108 \cdot 9 = 972.\]

\[n = 972 - 60 = 912\]

\[a = 60\ :12 = 5\]

\[b = 12 + 19 = 31\]

\[c = 155\ :31 = 5\]

\[d = 155 - 108 = 47\]

\[m = 972\ :108 = 9.\]

\[2)\ 100 + 92 = 192\ :12 =\]

\[= 16 + 32 = 48 \cdot 8 =\]

\[= 384 - 323 = 61 + 39 = 100\]

\[x = 192 - 100 = 92\]

\[y = 192\ :16 = 12\]

\[z = 16 + 32 = 48\]

\[p = 384\ :x = 384\ :48 = 8\]

\[m = 100 - 39 = 61\]

\[q = 384 - 61 = 323\]
