Question

х-(7 3/11-9/11)=2 4/11-1 5/11+8/11

Answer 1

$x - (7 \frac{3}{11} - \frac{9}{11} ) = 2 \: \frac{4}{11} - 1 \: \frac{5}{11} + \frac{8}{11} \\ \\ \\ x - ( \frac{80}{11} - \frac{ 9}{11} ) = \frac{26}{11} - \frac{16}{11} + \frac{8}{11} \\ \\ \\ x - ( \frac{71}{11} ) = \frac{10}{11} + \frac{8}{11} \\ \\ \\ x - \frac{71}{11} = \frac{18}{11} \\ \\ \\ x = \frac{18}{11} + \frac{71}{11} \\ \\ \\ x = \frac{89}{11} \\ \\ \\ \\ otvet : x = \frac{89}{11}$

Вот готово уравнение!
