Solución

Ha introducido [src]
a*x = a + 1 + x
$$a x = x + \left(a + 1\right)$$
Solución detallada
Tenemos una ecuación lineal:
a*x = a+1+x

Sumamos los términos semejantes en el miembro derecho de la ecuación:
a*x = 1 + a + x

Transportamos los términos con la incógnita a
del miembro derecho al izquierdo:
$$a x - a = x + 1$$
Dividamos ambos miembros de la ecuación en (-a + a*x)/a
a = 1 + x / ((-a + a*x)/a)

Obtenemos la respuesta: a = (1 + x)/(-1 + x)
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a x = a + x + 1$$
Коэффициент при a равен
$$x - 1$$
entonces son posibles los casos para x :
$$x < 1$$
$$x = 1$$
Consideremos todos los casos con detalles:
Con
$$x < 1$$
la ecuación será
$$- a - 1 = 0$$
su solución
$$a = -1$$
Con
$$x = 1$$
la ecuación será
$$-2 = 0$$
su solución
no hay soluciones
