Question

срочнооо помогите плиз​

Answer 1

$4\frac{5}{14}-(x-7\frac{3}{14})=2\frac{3}{14}\\\\4\frac{5}{14}-x+7\frac{3}{14}=2\frac{3}{14} \\\\\frac{61}{14}-x+\frac{101}{14}=\frac{31}{14}\\\\-x= \frac{31}{14}-\frac{61}{14}- \frac{101}{14}\\\\-x=-\frac{131}{14}\\\\x=\frac{131}{14}\\\\x=9\frac{5}{14}$

Проверка:

$4\frac{5}{14}-(9\frac{5}{14}-7\frac{3}{14})=2\frac{3}{14}\\\\4\frac{5}{14}-9\frac{5}{14}+7\frac{3}{14}=2\frac{3}{14}\\\\\frac{61}{14}- \frac{131}{14}+\frac{101}{14}= \frac{31}{14}\\\\-\frac{70}{14}+\frac{101}{14}=\frac{31}{14}\\\\\frac{31}{14}=\frac{31}{14}$
