Решение параметрического уравнения
Дано уравнение с параметром:
$$2 a x - 3 a = 4 x + 1$$
Коэффициент при x равен
$$2 a - 4$$
тогда возможные случаи для a :
$$a < 2$$

Рассмотри все случаи подробнее:
При
$$a < 2$$
уравнение будет
$$- 2 x - 4 = 0$$
его решение
$$x = -2$$
При
$$a = 2$$
уравнение будет
$$-7 = 0$$
