SUMMARY

The discussion focuses on solving a system of three equations: y^2 + (y*x) - z - x = 0, z^2 + (z*y) - x - y = 0, and x^2 + (x*z) - y - z = 0. The solution provided is x = y = z = 1, which satisfies all three equations. The equations represent a nonlinear system that can be approached using substitution or numerical methods for verification.

Find x, y, z solving all the three equations:

y^2 + (y*x) - z - x = 0z^2 + (z*y) - x - y = 0x^2 + (x*z) - y - z = 0I would be very grateful!
