$\frac{5}{13} \times (6.5x - 5. \frac{1}{5} y) - 2.4( \frac{5}{8} x - \\ \frac{5}{6} y) =$

$\frac{5}{13} \times \frac{65}{10} x - \frac{5}{13 } \times \frac{26}{5} y - \\ \frac{24}{10} \times \frac{5}{8} x + \frac{24}{10} \times \frac{5}{6} y =$

$\frac{5}{2} x - 2y - \frac{3}{2} x + 2y = \\ \frac{2}{2} x = x = 4.5$
