\[ax - 6a > 5x + 3\]
\[ax - 5x > 3 + 6a\]
\[(a - 5)x > 6a + 3\]
\[1)\ a = 5:\]
\[0 \cdot x > 33 \Longrightarrow нет\ решения.\]
\[2)\ a > 5:\]
\[x > \frac{6a + 3}{a - 5} \Longrightarrow\]
\[\Longrightarrow x \in \left( \frac{6a + 3}{a - 5}; + \infty \right).\]
\[3)\ a < 5:\]
\[x < \frac{6a + 3}{a - 5} \Longrightarrow x \in \left( - \infty;\frac{6a + 3}{a - 5} \right).\]
\[Ответ:\ \ нет\ решения\ для\ a = 5;\]
\[\ \ \ \ \ \ \ \ \ \ \ \ \ \ любое\ x \in \left( \frac{6a + 3}{a - 5}; + \infty \right)\ \]
\[\ для\ a > 5;\]
\[\ \ \ \ \ \ \ \ \ \ \ \ \ \ любое\ x \in \left( - \infty;\frac{6a + 3}{a - 5} \right)\text{\ \ }\]
\[для\ a < 5.\]
