Решите задачу:

$\frac{13}{5} - ( \frac{7}{6} + x) = \frac{11}{15} \\ \frac{7}{6} + x = \frac{13}{5} - \frac{11}{15} \\ \frac{7}{6} + x = \frac{39 - 11}{15} \\ \frac{7}{6} + x = \frac{28}{15} \\ x = \frac{28}{15} - \frac{7}{6} \\ x = \frac{56 - 35}{30} \\ x = \frac{21}{30} \\ x = \frac{7}{10}$

$(x - \frac{3}{4} ) + \frac{7}{16} = \frac{9}{16} \\ x - \frac{3}{4} = \frac{9}{16} - \frac{7}{16} \\ x - \frac{3}{4} = \frac{2}{16} \\ x - \frac{3}{4} = \frac{1}{8} \\ x = \frac{3}{4} + \frac{1}{8} \\ x = \frac{6 + 1}{8} \\ x = \frac{7}{8}$
