\[\left| x - \frac{7}{3} \right| - \frac{5}{3};\ \ x = \frac{3}{5}:\]
\[\left| \frac{3^{\backslash 3}}{5} - \frac{7^{\backslash 5}}{3} \right| - \frac{5}{3} = \left| \frac{9 - 35}{15} \right| - \frac{5}{3} =\]
\[= \left| - \frac{26}{15} \right| - \frac{5^{\backslash 5}}{3} = \frac{26}{15} - \frac{25}{15} = \frac{1}{15}.\]
