Solve the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations. x + y - z = -2 2x - y + 3z = 9 x - 4y - 2z = 1

Solving the system of equations by finding the reduced row-echelon form of the augmented matrix for the system of equations, we get:

x = 1, y = -1, and z = 2

Step-by-step explanation:

Please, see the attached file.

Thanks.

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
