Question

(x-9 3/7)+5 8/21= 6 5/14 решите уравнение пожалуйста

Answer 1

$(x - 9 \frac{3}{7} ) + 5 \frac{8}{21} = 6 \frac{5}{14} \\ (x - \frac{66} {7} ) + \frac{113}{21} = \frac{89}{14} \\ x - \frac{66}{7} + \frac{113}{21} = \frac{89}{14} \\ x - \frac{85}{21} = \frac{89}{14} \\ x = \frac{89}{14} + \frac{85}{21} \\ x = \frac{437}{42} \\ x = 10 \frac{17}{42}$
