\[x - 3,8\]
\[x = 1,2:\]
\[1,2 - 3,8 = - 2,6.\]
\[x = 3,8:\]
\[3,8 - 3,8 = 0.\]
\[x = - 4\frac{1}{3} = - \frac{13}{3}:\]
\[- \frac{13}{3} - 3,8 = - \frac{13}{3} - \frac{38}{10} =\]
\[= - \frac{13^{\backslash 5}}{3} - \frac{19^{\backslash 3}}{5} = - \frac{65}{15} - \frac{57}{15} =\]
\[= - \frac{122}{15} = - 8\frac{2}{15}.\]
