What do you mean by "getting the answers by checking"?I need help to solve this system of equations:
x^2 + y^2 - z(x+y) = 10
y^2 + z^2 - x(y+z) = 6
z^2 + x^2 - y(z+x) = -2
I got the answer by checking. There are two answers. (1, 3, 0) and (-1, -3, 0)
Knowing the answer helps. Since z=0 in both solutions, the third equation must beI need help to solve this system of equations. I got the answer by checking) There are two answers. (1;3;0) and (-1;-3;0)
