Solución detallada
Tenemos una ecuación lineal:
a*x+b-b = c-b
Sumamos los términos semejantes en el miembro izquierdo de la ecuación:
a*x = c-b
Sumamos los términos semejantes en el miembro derecho de la ecuación:
a*x = c - b
Dividamos ambos miembros de la ecuación en a
x = c - b / (a)
Obtenemos la respuesta: x = (c - b)/a
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a x = - b + c$$
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
$$b - c - x = 0$$
su solución
$$x = b - c$$
Con
$$a = 0$$
la ecuación será
$$b - c = 0$$
