Math 141: PRACTICE TEST # 1: Chapter 1 KEY

Consistent system x + 2y + 8z = 0, y + 3z = 2, 0 = 0 (dependent solution) Solve for x and y in terms of z ( x = -2y – 8z; y = - 3z + 2; z can be any real number C. Inconsistent system No solution because last row 0 = 3 is a false statement. ................
