Solución

Ha introducido [src]
x*y = y + 2
$$x y = y + 2$$
Solución detallada
Tenemos una ecuación lineal:
x*y = y+2

Dividamos ambos miembros de la ecuación en y
x = 2 + y / (y)

Obtenemos la respuesta: x = (2 + y)/y
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$x y = y + 2$$
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
$$- x - 1 = 0$$
su solución
$$x = -1$$
Con
$$y = 0$$
la ecuación será
$$-2 = 0$$
su solución
no hay soluciones
