Solución
Solución detallada
Tenemos una ecuación lineal:
Dividamos ambos miembros de la ecuación en a
Obtenemos la respuesta: x = -(c + b*y)/a
a*x = -b*y-c
Dividamos ambos miembros de la ecuación en a
x = -c - b*y / (a)
Obtenemos la respuesta: x = -(c + b*y)/a
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a x = - b y - c$$
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
$$a x = - b y - c$$
