Answer 1

Ответ:

$\frac{5}{3} ( \frac{5}{8} + x) = \frac{31}{482} \\ ( \frac{5}{3} \times \frac{5}{8} ) + \frac{5}{3} x = \frac{31}{482} \\ \frac{25}{24} + \frac{5}{3} x = \frac{31}{482} \\ \frac{5}{3} x = \frac{31}{482} - \frac{25}{24} \\ \frac{5}{3} x = \frac{372 - 6025}{5784} \\ \frac{5}{3} x = - \frac{5653}{5784} \\ x = - \frac{5653}{5784} \div \frac{5}{3} \\ x = - \frac{5653 \times 3}{5784 \times 5} \\ x = - \frac{5653}{1928 \times 5} \\ x = - \frac{5653}{9640}$
