The solution x=1 is obvious .To get the other solution take the log of both sides and solve the quadratic equation . It of course
has the also solution x=1 ,the other is negative.
The -1.691 is actually much closer to an approximate -1.6826 if you calculate it out. It makes a big difference in the final solution.
