\[1)\ (x - 5) + 2i\]
\[x - 5 = 0\]
\[x = 5.\]
\[Ответ:\ \ 5.\]
\[2)\ \left( x + \frac{1}{3} \right) - i\]
\[x + \frac{1}{3} = 0\]
\[x = - \frac{1}{3}.\]
\[Ответ:\ - \frac{1}{3}.\]
\[3)\ (2x + 1) - 3i\]
\[2x + 1 = 0\]
\[2x = - 1\]
\[x = - \frac{1}{2}.\]
\[Ответ:\ - \frac{1}{2}.\]
\[4)\ (3x - 5) + 4i\]
\[3x - 5 = 0\]
\[3x = 5\]
\[x = 1\frac{2}{3}.\]
\[Ответ:\ \ 1\frac{2}{3}.\]
