Solución detallada
Tenemos una ecuación lineal:
x+y = 3*x2-x*y-y2
Sumamos los términos semejantes en el miembro izquierdo de la ecuación:
x + y = 3*x2-x*y-y2
Sumamos los términos semejantes en el miembro derecho de la ecuación:
x + y = -y2 + 3*x2 - x*y
Move the summands with the other variables
del miembro izquierdo al derecho, obtenemos:
$$x = - x y + 3 x_{2} - y - y_{2}$$
Obtenemos la respuesta: x = (-y - y2 + 3*x2)/(1 + y)
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$x + y = - x y + 3 x_{2} - y_{2}$$
Коэффициент при x равен
$$y + 1$$
entonces son posibles los casos para y :
$$y < -1$$
$$y = -1$$
Consideremos todos los casos con detalles:
Con
$$y < -1$$
la ecuación será
$$- x - 3 x_{2} + y_{2} - 2 = 0$$
su solución
$$x = - 3 x_{2} + y_{2} - 2$$
Con
$$y = -1$$
la ecuación será
$$- 3 x_{2} + y_{2} - 1 = 0$$
su solución
