Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$a x - a = 1$$
Коэффициент при a равен
$$x - 1$$
entonces son posibles los casos para x :
$$x < 1$$
$$x = 1$$
Consideremos todos los casos con detalles:
Con
$$x < 1$$
la ecuación será
$$- a - 1 = 0$$
su solución
$$a = -1$$
Con
$$x = 1$$
la ecuación será
$$-1 = 0$$
su solución

$$a_{1} = \frac{\operatorname{re}{\left(x\right)} - 1}{\left(\operatorname{re}{\left(x\right)} - 1\right)^{2} + \left(\operatorname{im}{\left(x\right)}\right)^{2}} - \frac{i \operatorname{im}{\left(x\right)}}{\left(\operatorname{re}{\left(x\right)} - 1\right)^{2} + \left(\operatorname{im}{\left(x\right)}\right)^{2}}$$
a1 = (re(x) - 1)/((re(x) - 1)^2 + im(x)^2) - i*im(x)/((re(x) - 1)^2 + im(x)^2)
