Вопрос:

Ответ:

\[3x - 2 = 6x + 5\]

\[3x - 6x = 5 + 2\]

\[- 3x = 7\]

\[x = - \frac{7}{3}\]

\[x = - 2\frac{1}{3} \Longrightarrow корень.\]

\[1)\ 17 \cdot (3x - 2) = 17 \cdot (6x + 5)\]

\[3x - 2 = 6x + 5\]

\[3x - 6x = 5 + 2\]

\[- 3x = 7\]

\[x = - \frac{7}{3}\]

\[x = - 2\frac{1}{3}.\]

\[2)\ 6x - 3x = 5 - 2\]

\[3x = 3\]

\[x = 3\ :3\]

\[x = 1.\]

\[3)\ \frac{3x - 2}{19} = \frac{6x + 5}{19}\]

\[3x - 2 = 6 + 5\]

\[3x - 6x = 5 + 2\]

\[- 3x = 7\]

\[x = - \frac{7}{3}\]

\[x = - 2\frac{1}{3}.\]
