Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$x y - 3 y = -1$$
Коэффициент при x равен
$$y$$
entonces son posibles los casos para y :
$$y < 0$$
$$y = 0$$
Consideremos todos los casos con detalles:
Con
$$y < 0$$
la ecuación será
$$4 - x = 0$$
su solución
$$x = 4$$
Con
$$y = 0$$
la ecuación será
$$1 = 0$$
su solución
no hay soluciones
