Indeed, the system has the following solutions

(1, 1-1/√2, 1+1/√2)

(1-1/√2, 1, 1+1/√2)

(1-1/√2, 1+1/√2, 1)

You are right, they are between 1-1/√2 and 1+1/√2.

I coud describe solution, but the question didn't ask how to solve. It easier by hand in paper.

Just I moved to a new system of coordinate shifting x, y znd z by 1, then it made easier to solve.
