Solución

Ha introducido [src]
a*x + 3*y = 5
$$a x + 3 y = 5$$
Solución detallada
Tenemos una ecuación lineal:
a*x+3*y = 5

Dividamos ambos miembros de la ecuación en (3*y + a*x)/x
x = 5 / ((3*y + a*x)/x)

Obtenemos la respuesta: x = (5 - 3*y)/a
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a x + 3 y = 5$$
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
$$- x + 3 y - 5 = 0$$
su solución
$$x = 3 y - 5$$
Con
$$a = 0$$
la ecuación será
$$3 y - 5 = 0$$
su solución
