Use the Gauss-Jordan method to solve the system of equations. If the system has infinitely many solutions, let the last
variable be the arbitrary variable.
-$ 4 x-5 y-7 z=-1 $
$ -7 x+2 y-8 z=1 $
$ 20 x-25 y-35 z=-5 $
A) $ \{(-5 z+2,4 z-25, z)\} $
B) $ \{(-1,1,-5)\} $
C) $ \varnothing $
D) $ \{(5,5,-1)\} $
