Решите уравнение: 4 5/39-(t+1 7/26)=2 13/13.

\[4\frac{5}{39} - \left( t + 1\frac{7}{26} \right) = 2\frac{3}{13}\]

\[t + 1\frac{7}{26} = 4\frac{5}{39} - 2\frac{3}{13}\]

\[t = 4\frac{5^{\backslash 2}}{39} - 2\frac{3^{\backslash 6}}{13} - 1\frac{7^{\backslash 3}}{26}\]

\[t = 4\frac{10}{78} - 2\frac{18}{78} - 1\frac{21}{78}\]

\[t = 3\frac{88}{78} - 3\frac{39}{78}\]

\[t = \frac{49}{78}.\]
