Solución
Solución detallada
Tenemos una ecuación lineal:
Dividamos ambos miembros de la ecuación en (b + a*x)/x
Obtenemos la respuesta: x = (c - b)/a
a*x+b = c
Dividamos ambos miembros de la ecuación en (b + a*x)/x
x = c / ((b + a*x)/x)
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
$$b - c = 0$$
su solución
$$a x + b = c$$
