\[1)\ 51 - k = 9 \cdot 3\]

\[51 - k = 27\]

\[k = 51 - 27\]

\[k = 24.\]

\[\overline{51 - 24 = 9 \cdot 3}\]

\[27 = 27.\]

\[2)\ x - 16 = 72\ :8\]

\[x - 16 = 9\]

\[x = 9 + 16\]

\[x = 25.\]

\[\overline{25 - 16 = 72\ :8}\]

\[9 = 9.\]

\[3)\ a + 25 = 6 \cdot 7\]

\[a + 25 = 42\]

\[a = 42 - 25\]

\[a = 17.\]

\[\overline{17 + 25 = 6 \cdot 7}\]

\[42 = 42.\]
