Решение параметрического уравнения
Дано уравнение с параметром:
$$4 = a - b x + 1$$
Коэффициент при x равен
$$b$$
тогда возможные случаи для b :
$$b < 0$$
$$b = 0$$
Рассмотри все случаи подробнее:
При
$$b < 0$$
уравнение будет
$$- a - x + 3 = 0$$
его решение
$$x = 3 - a$$
При
$$b = 0$$
уравнение будет
$$3 - a = 0$$
его решение
