Solución detallada
Tenemos una ecuación lineal:
a*x+8 = a
Transportamos los términos libres (sin x)
del miembro izquierdo al derecho, obtenemos:
$$a x = a - 8$$
Dividamos ambos miembros de la ecuación en a
x = -8 + a / (a)
Obtenemos la respuesta: x = (-8 + a)/a
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a x + 8 = a$$
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
$$9 - x = 0$$
su solución
$$x = 9$$
Con
$$a = 0$$
la ecuación será
$$8 = 0$$
su solución
no hay soluciones
