Ответ:

-х=19/6-21/5

-х=-31/30

х=31/30або 1 1/30

Answer 2

Ответ:

$4.2 - x = 3 \frac{1}{6}$

$4.2 - x = \frac{3 \times 6 + 1}{6}$

$4.2 - x = \frac{19}{6}$

$- x = \frac{19}{6} - 4.2$

$- x = \frac{19}{6} - \frac{21}{5}$

$- x = \frac{95 - 126}{30}$

$- x = \frac{ - 31}{30}$

$- x = - \frac{31}{30}$

$x = \frac{31}{30}$
