Вопрос:

Решите уравнение: 3/5*x=0,2x-11/35.

Ответ:

\[\frac{3}{5}x = 0,2x - \frac{11}{35}\]

\[\frac{3}{5}x - 0,2x = - \frac{11}{35}\]

\[\frac{3}{5}x - \frac{1}{5}x = - \frac{11}{35}\]

\[\frac{2}{5}x = - \frac{11}{35}\]

\[x = - \frac{11}{35}\ :\frac{2}{5} = - \frac{11}{35} \cdot \frac{5}{2}\]

\[x = - \frac{11}{14}.\]
