Answer 1

Ответ:

$- 7 \frac{3}{5} x = \frac{19}{25} \\ - \frac{38}{5} x = \frac{19}{25} \\ x = \frac{19}{25} \times ( - \frac{5}{38} ) \\ x = \frac{1}{5} \times ( - \frac{1}{2} ) \\ x = - 0.1$

Answer 2

$- 7 \frac{3}{5} x = \frac{19}{25} \\ \\ - \frac{38}{5} x = \frac{19}{25} \\ \\ x=-(\frac{19}{25}\cdot \frac{5}{38}) \\ \\ x=-\frac{1}{10}\;\;( ili \;\;x= -0,1\;\; ili\;\; x=-10^{-1})$
