Question

8-(х-6 10/19)=2 5/19​

Answer 1

$8 - (x - 6 \frac{10}{19} ) = 2 \frac{5}{19} \\ x - 6 \frac{10}{19} = 8 - 2 \frac{5}{19 } \\ x - 6 \frac{10}{19} = 7 \frac{19}{19} - 2 \frac{5}{19} \\ x - 6 \frac{10}{19} = 5 \frac{14}{19} \\ x = 5 \frac{14}{19} + 6 \frac{10}{19} \\ x = 11 \frac{24}{19} \\ x = 12 \frac{5}{19}$

Answer 2

Ответ:

$x = 12 \frac{5}{19}$

Пошаговое объяснение:

$8 - (x - 6 \frac{10}{19} ) = 2 \frac{5}{19}$

$8 - (x - \frac{124}{19} ) = \frac{43}{19}$

$8 - x + \frac{124}{19} = \frac{43}{19}$

$\frac{276}{19} - x = \frac{43}{19}$

$- x = \frac{43}{19} - \frac{276}{19}$

$- x = - \frac{233}{19}$

$x = \frac{233}{19}$

$x= 12 \frac{5}{19}$

Проверка:

_________________________

$8 - ( \frac{233}{19} - \frac{124}{19} ) = \frac{43}{19}$

$\frac{43}{19} = \frac{43}{19}$
