\/ x *y = x
$$\sqrt[3]{x} y = x$$
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$\sqrt[3]{x} y = x$$
Коэффициент при y равен
$$\sqrt[3]{x}$$
entonces son posibles los casos para x :
$$x < 0$$
$$x = 0$$
Consideremos todos los casos con detalles:
Con
$$x < 0$$
la ecuación será
$$\sqrt[3]{-1} y + 1 = 0$$
su solución
Con
$$x = 0$$
la ecuación será
$$0 = 0$$
su solución
cualquiera y
