Solve the system
x+2y+z=82x−y+3z=93x+y−2z=−1\begin{aligned} x + 2y + z &= 8 \\ 2x - y + 3z &= 9 \\ 3x + y - 2z &= -1 \end{aligned}x+2y+z2x−y+3z3x+y−2z=8=9=−1
Which ordered triple (x,y,z)(x, y, z)(x,y,z) is the solution?
Select all that apply.
(1, 2, 3)(1,\; 2,\; 3)(1,2,3)
(3, 2, 1)(3,\; 2,\; 1)(3,2,1)
(1, 3, 2)(1,\; 3,\; 2)(1,3,2)
(1, 2, −3)(1,\; 2,\; -3)(1,2,−3)
