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. $\left[\begin{array}{llll}1&0&0&:2\\0 & 1 & 0 & :3 \\0 & 0 & 1 & :4\end{array}\right]$

A) x = 0,y = 0,z = 0
B) x = 2x,y = 4y,z = 3z
C) x = 2,y = 3,z = 4
D) x = -2,y = -3,z = -4
E) x = 2,y = 0,z = 0
