Solve by matrix method : x + 2y + z = 7, x + 3z= 11, -3y + 2x = 1.

Solve by matrix method : x + 2y = 7, y + 2z = 4, z + 2x= 7.

Solve the following system of linear equations by matrix method : 3x - 2y + 3z = 8, 2x + y - z = 1, 4x - 3y + 2z = 4

Solve by matrix method 3x - 2y + 3z =8 2x + y - z =1 4x -3y +2z =4

Solve by matrix method 3x + 2y + z= 1000, 4x + y+ 3z = 1500, and x + y + z = 600
