Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$x \left(a + 3\right) = a - 5$$
Коэффициент при x равен
$$a + 3$$
entonces son posibles los casos para a :
$$a < -3$$
$$a = -3$$
Consideremos todos los casos con detalles:
Con
$$a < -3$$
la ecuación será
$$9 - x = 0$$
su solución
$$x = 9$$
Con
$$a = -3$$
la ecuación será
$$8 = 0$$
su solución
no hay soluciones
