# Augmented MATRIX HELP!

(1 pt) The following system has an infinite number of solutions. Form an augmented matrix, then write the matrix in the reduced form. Write the reduced form of the matrix below and then write the solution in terms of z.

3x + 2y + 4z = 4

6x - 4y + 3z = 3

9x − 2y + 7z = 7

The required augmented matrix is:

a11 a12 a13 b1

a21 a22 a23 b2

a31 a32 a33 b3

where

a11 = , a12 = , a13 = , b1 =

a21 = , a22 = , a23 = , b2 =

a31 = , a32 = , a33 = , b3 = ,

and x = y=
