Solución

Ha introducido [src]
2*tan(5*x) = -2
$$2 \tan{\left(5 x \right)} = -2$$
Solución detallada
Tenemos la ecuación
$$2 \tan{\left(5 x \right)} = -2$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en 2

La ecuación se convierte en
$$\tan{\left(5 x \right)} = -1$$
Esta ecuación se reorganiza en
$$5 x = \pi n + \operatorname{atan}{\left(-1 \right)}$$
O
$$5 x = \pi n - \frac{\pi}{4}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$5$$
obtenemos la respuesta:
$$x_{1} = \frac{\pi n}{5} - \frac{\pi}{20}$$
