Solución
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$y = - \frac{3 x}{y} + 2 y$$
Коэффициент при x равен
$$\frac{3}{y}$$
entonces son posibles los casos para y :
Consideremos todos los casos con detalles:
2 2
im (y) re (y) 2*I*im(y)*re(y)
x1 = - ------ + ------ + ---------------
3 3 3
$$x_{1} = \frac{\left(\operatorname{re}{\left(y\right)}\right)^{2}}{3} + \frac{2 i \operatorname{re}{\left(y\right)} \operatorname{im}{\left(y\right)}}{3} - \frac{\left(\operatorname{im}{\left(y\right)}\right)^{2}}{3}$$
x1 = re(y)^2/3 + 2*i*re(y)*im(y)/3 - im(y)^2/3
