$$\cos{\left(- \frac{5 x}{6} + \pi \right)} = \frac{\left(-1\right) \sqrt{3}}{2}$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(- \frac{5 x}{6} + \pi \right)} = \frac{\left(-1\right) \sqrt{3}}{2}$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en -1

La ecuación se convierte en
$$\cos{\left(\frac{5 x}{6} \right)} = \frac{\sqrt{3}}{2}$$
Esta ecuación se reorganiza en
$$\frac{5 x}{6} = \pi n + \operatorname{acos}{\left(\frac{\sqrt{3}}{2} \right)}$$
$$\frac{5 x}{6} = \pi n - \pi + \operatorname{acos}{\left(\frac{\sqrt{3}}{2} \right)}$$
O
$$\frac{5 x}{6} = \pi n + \frac{\pi}{6}$$
$$\frac{5 x}{6} = \pi n - \frac{5 \pi}{6}$$
, donde n es cualquier número entero
Dividamos ambos miembros de la ecuación obtenida en
$$\frac{5}{6}$$
obtenemos la respuesta:
$$x_{1} = \frac{6 \pi n}{5} + \frac{\pi}{5}$$
$$x_{2} = \frac{6 \pi n}{5} - \pi$$
