\[2ax - 3 = 5a - 4x\]
\[2ax + 4x = 5a + 3\]
\[2x(a + 2) = 5a + 3\]
\[x = \frac{5a + 3}{2(a + 2)}\]
\[a = - 2:\]
\[нет\ решения,\ так\ как\]
\[2x( - 2 + 2) = 5 \cdot ( - 2) + 3\]
\[0x \neq - 7.\]
\[a \neq - 2:\]
\[x = \frac{5a + 3}{2 \bullet (a + 2)}.\]
\[Ответ:\ нет\ решения\ при\]
\[\ a = - 2;\ \]
\[\ \ \ \ \ \ \ \ \ \ \ \ \ \ x = \frac{5a + 3}{2 \bullet (a + 2)}\ \ при\ \]
\[a \neq - 2.\]
