An Augmented Matrix That Represents a System of Linear Equations

Multiple Choice

An augmented matrix that represents a system of linear equations (in variables x, y, and z) has been reduced using Gauss-Jordan elimination. Write the solution represented by the augmented matrix.

A) x = 0, y = 0, z = 0
B) x = -5x, y = -4y, z = -3z
C) x = -5, y = -3, z = -4
D) x = 5, y = 3, z = 4
E) x = -5, y = 0, z = 0
