Solución detallada
Tenemos la ecuación
$$\log{\left(y + 1 \right)} = c - \log{\left(x - 1 \right)}$$
$$\log{\left(y + 1 \right)} = c - \log{\left(x - 1 \right)}$$
Es la ecuación de la forma:
log(v)=p
Por definición log
v=e^p
entonces
$$y + 1 = e^{\frac{c - \log{\left(x - 1 \right)}}{1}}$$
simplificamos
$$y + 1 = \frac{e^{c}}{x - 1}$$
$$y = -1 + \frac{e^{c}}{x - 1}$$
