Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$c x - x = 10$$
Коэффициент при x равен
$$c - 1$$
entonces son posibles los casos para c :
$$c < 1$$
$$c = 1$$
Consideremos todos los casos con detalles:
Con
$$c < 1$$
la ecuación será
$$- x - 10 = 0$$
su solución
$$x = -10$$
Con
$$c = 1$$
la ecuación será
$$-10 = 0$$
su solución
no hay soluciones
