Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a x = 2 a - 1$$
Коэффициент при x равен
$$a$$
entonces son posibles los casos para a :
$$a < 0$$
$$a = 0$$
Consideremos todos los casos con detalles:
Con
$$a < 0$$
la ecuación será
$$3 - x = 0$$
su solución
$$x = 3$$
Con
$$a = 0$$
la ecuación será
$$1 = 0$$
su solución
no hay soluciones
