Solución
Solución detallada
Tenemos una ecuación lineal:
Dividamos ambos miembros de la ecuación en (c + a*x + b*y)/x
Obtenemos la respuesta: x = -(c + b*y)/a
a*x+b*y+c = 0
Dividamos ambos miembros de la ecuación en (c + a*x + b*y)/x
x = 0 / ((c + a*x + b*y)/x)
Obtenemos la respuesta: x = -(c + b*y)/a
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a x + b y + c = 0$$
Коэффициент при x равен
$$a$$
entonces son posibles los casos para a :
$$a < 0$$
$$a = 0$$
Consideremos todos los casos con detalles:
Con
$$a < 0$$
la ecuación será
$$b y + c - x = 0$$
su solución
$$x = b y + c$$
Con
$$a = 0$$
la ecuación será
$$b y + c = 0$$
su solución
$$a x + b y + c = 0$$
