What do w, x, y and z equal in this matrix equation?

• w = 13, x = 4, y = 7, z = 23

• w = 13, x = -4, y = 11, z = 23

• w = 13, x = 4, y = 11, z = 23

• w = 13, x = 4, y = 11, z = 17

Solve the system of equations using matrices: 3x + 2y - z = 11, 2x - y + 3z = 4, and x + 3y - 2z = 9.

• The solution for the system of equations is x = 3, y = 2, and z = 1.

• The solution for the system of equations is x = 3, y = 1, and z = 2.

• The solution for the system of equations is x = 2, y = 3, and z = 1.

• The solution for the system of equations is x = 1, y = 3, and z = 2.
