Solución

Ha introducido [src]
         x        
log(y) + - - 3 = 0
         y        
$$\left(\frac{x}{y} + \log{\left(y \right)}\right) - 3 = 0$$
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$\frac{x}{y} + \log{\left(y \right)} - 3 = 0$$
Коэффициент при x равен
$$\frac{1}{y}$$
entonces son posibles los casos para y :
Consideremos todos los casos con detalles:

x1 = I*((3 - log(|y|))*im(y) - arg(y)*re(y)) + (3 - log(|y|))*re(y) + arg(y)*im(y)
$$x_{1} = \left(3 - \log{\left(\left|{y}\right| \right)}\right) \operatorname{re}{\left(y\right)} + i \left(\left(3 - \log{\left(\left|{y}\right| \right)}\right) \operatorname{im}{\left(y\right)} - \operatorname{re}{\left(y\right)} \arg{\left(y \right)}\right) + \operatorname{im}{\left(y\right)} \arg{\left(y \right)}$$
x1 = (3 - log(|y|))*re(y) + i*((3 - log(|y|))*im(y) - re(y)*arg(y)) + im(y)*arg(y)
