Answer:

-10x + 6y + 2z = -30 10x + 2y + 8z = 18 8y + 10z = -12 4y + 5z = -6 -15x + 9y + 3z = -45 15x + 5y + 7z = 9 14y + 10z = -36 7y + 5z = -18 7y + 5z = -18 -4y - 5z = 6  8x-9y=72. 8x−9y=72 8 x - 9 y = 72. 3y - 3y x?+6x=2x-4 x²+4X=-4 x2+4x +4= 0. (x+2)(x+2) =0. X=-2 x=-2 ... 6-3x = 4x + 4. . 2=7x -. - 4-2=34+12. - ý 2=2y+12. +. 3X= 12-X.
