Question

Given the following system of equations,

a) build an augmented matrix to represent the system of equations,

b) show the elementary row operations that lead to a reduced row form, and

c) find the solutions to this system of equations

After completing parts a–c enter the solution* to x in the box.

x+2y+z=−8

4x−y+z=25

x+4y−3z=−2

*If there is a free variable, set 

z=t and if the system is inconsistent type "inconsistent" in the box.]

x= ?
