Me i beg you plea solve 2x + y + z = 5 4x – 2y – z = 0 3x – y + 2z = 6 (1, 1, 2) (-1, -1, -2) (5, 0, 6) (1, 1, -2) solve 3x + 6y – 6z = 9 2x – 5y + 4z = 6 -x +16y + 14z = -3 (5, 0, 1) (9, 6, -3) (0, 3, 0) (3, 0, 0) solve –x + y + 2z = 2 2x – y + z = 5 -4x – y + 3z = 3 (2, 5, 3) (0, 4, -1) (1, -1, 2) (-1, 1, -2) solve –x + 3y + z = 9 2x + 5y = 27 3x + y – 2z = -18 (1, 3, -2) (21, -3, 39) (1, 2, -4) (22, -1, 26) solve x – 2y – 3z = 3 3x + y + z = 12 3x – 2y – 4z = 15 (0, 0, -1) (3, 12, 15) (3, 9, -6) (-3, -9, 6) solve x + 3y + z = 1 2x – y – z = 6 5x + y + z = 1 (1, 6, 1) (1, 2, -6) (2, 1, -4) (-1, -2, 6)
