Solución

Ha introducido [src]
        /d              \    -x
(1 - x)*|--(y(x)) + y(x)| = e  
        \dx             /      
$$\left(1 - x\right) \left(y{\left(x \right)} + \frac{d}{d x} y{\left(x \right)}\right) = e^{- x}$$
(1 - x)*(y + y') = exp(-x)
Respuesta [src]
                           -x
y(x) = (C1 - log(-1 + x))*e  
$$y{\left(x \right)} = \left(C_{1} - \log{\left(x - 1 \right)}\right) e^{- x}$$
