log\y  - 2/ = c + -
                  x
$$\log{\left(y^{2} - 2 \right)} = c + \frac{1}{x}$$
Solución detallada
Tenemos la ecuación:
$$\log{\left(y^{2} - 2 \right)} = c + \frac{1}{x}$$
Usamos la regla de proporciones:
De a1/b1 = a2/b2 se deduce a1*b2 = a2*b1,
En nuestro caso
a1 = 1

b1 = 1/(-c + log(-2 + y^2))

a2 = 1

b2 = x

signo obtendremos la ecuación
$$x = \frac{1}{- c + \log{\left(y^{2} - 2 \right)}}$$
$$x = \frac{1}{- c + \log{\left(y^{2} - 2 \right)}}$$
Abrimos los paréntesis en el miembro derecho de la ecuación
x = -1/c+1/log-1/2+1/y+1/2)

Sumamos los términos semejantes en el miembro derecho de la ecuación:
x = 1/(-c + log(-2 + y^2))

Obtenemos la respuesta: x = -1/(c - log(-2 + y^2))
