El profesor se sorprenderá mucho al ver tu solución correcta😉
Solución
x1 = 7/10 + cos(-1 + re(y))*cosh(im(y)) - I*sin(-1 + re(y))*sinh(im(y))
$$x_{1} = - i \sin{\left(\operatorname{re}{\left(y\right)} - 1 \right)} \sinh{\left(\operatorname{im}{\left(y\right)} \right)} + \cos{\left(\operatorname{re}{\left(y\right)} - 1 \right)} \cosh{\left(\operatorname{im}{\left(y\right)} \right)} + \frac{7}{10}$$
x1 = -i*sin(re(y) - 1)*sinh(im(y)) + cos(re(y) - 1)*cosh(im(y)) + 7/10
