solve the system of linear equations, using the gauss-jordan elimination method. (if there is no solution, enter no solution. if there are infinitely many solutions, express your answer in terms of the parameters t and/or s.)
x + 2y + z = −4
−2x − 3y − z = 2
2x + 4y + 2z = −8
(x, y, z) =

The system of linear equations has infinitely many solutions. x=t, y=2-t and z=t-8.

Step-by-step explanation:

The given educations are

Using the Gauss-Jordan elimination method, we get

Since elements of bottom row are 0, therefore the system of equations have infinitely many solutions.

Let x=t

The value of y is 2-t.

The value of z is t-8.

Therefore the he system of linear equations has infinitely many solutions. x=t, y=2-t and z=t-8.
