Решите уравнение: (3.6-2.5х)*1 5/7-5/7=1.6

[latex](3,6-2,5x)*1 \frac{5}{7} - \frac{5}{7} =1,6 \\ ( \frac{36}{10} - \frac{25}{10}x)* \frac{12}{7} - \frac{5}{7} = \frac{16}{10} \\ \frac{216}{35} - \frac{30}{7} x- \frac{5}{7} = \frac{8}{5} \\ - \frac{30}{7} x= \frac{8}{5} - \frac{216}{35} + \frac{5}{7} \\ - \frac{30}{7} x= - \frac{27}{7} \\ x=- \frac{27}{7} *(- \frac{7}{30} ) \\ x= \frac{9}{10} =0,9[/latex]
