\[\boxed{\mathbf{16.}}\]

\[28 + x = 55\]

\[x = 55 - 28\]

\[x = 27.\]

\[Проверка.\]

\[28 + 27 = 55\]

\[55 = 55.\]

\[x + 17 = 62\]

\[x = 62 - 17\]

\[x = 45.\]

\[Проверка.\]

\[45 + 17 = 62\]

\[62 = 62.\]

\[x + 36 = 84\]

\[x = 84 - 36\]

\[x = 48.\]

\[Проверка.\]

\[48 + 36 = 84\]

\[84 = 84.\]

\[49 + x = 73\]

\[x = 73 - 49\]

\[x = 24.\]

\[Проверка.\]

\[49 + 24 = 73\]

\[73 = 73.\]

\[66 + x = 71\]

\[x = 71 - 66\]

\[x = 5.\]

\[Проверка.\]

\[66 + 5 = 71\]

\[71 = 71.\]

\[x + 83 = 92\]

\[x = 92 - 83\]

\[x = 9.\]

\[Проверка.\]

\[9 + 83 = 92\]

\[92 = 92.\]
