            2    
sin(y) = x*y  + 5
$$\sin{\left(y \right)} = x y^{2} + 5$$
Solución detallada
Tenemos la ecuación
$$\sin{\left(y \right)} = x y^{2} + 5$$
cambiamos
$$- x y^{2} + \sin{\left(y \right)} - 6 = 0$$
$$- x y^{2} + \sin{\left(y \right)} - 6 = 0$$
Sustituimos
$$w = \sin{\left(y \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w - x y^{2} = 6$$
Dividamos ambos miembros de la ecuación en (w - x*y^2)/w
w = 6 / ((w - x*y^2)/w)

Obtenemos la respuesta: w = 6 + x*y^2
hacemos cambio inverso
$$\sin{\left(y \right)} = w$$
sustituimos w:
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$\sin{\left(y \right)} = x y^{2} + 5$$
Коэффициент при x равен
$$- y^{2}$$
entonces son posibles los casos para y :
$$y < 0$$
$$y = 0$$
Consideremos todos los casos con detalles:
Con
$$y < 0$$
la ecuación será
$$- x - 5 - \sin{\left(1 \right)} = 0$$
su solución
$$x = -5 - \sin{\left(1 \right)}$$
Con
$$y = 0$$
la ecuación será
$$-5 = 0$$
su solución
