Ha introducido [src]
 -y             
e   = c - log(x)
$$e^{- y} = c - \log{\left(x \right)}$$
Solución detallada
Tenemos la ecuación
$$e^{- y} = c - \log{\left(x \right)}$$
Transpongamos la parte derecha de la ecuación miembro izquierdo de la ecuación con el signo negativo
$$\log{\left(x \right)} = c - e^{- y}$$
Es la ecuación de la forma:
log(v)=p

Por definición log
v=e^p

entonces
$$x = e^{\frac{c - e^{- y}}{1}}$$
simplificamos
$$x = e^{c - e^{- y}}$$
