`2x+3y+z=11 , x+2y+z=8 , x-y+z=2`

Solve 3x-y+2z=12, x+2y+3z=11, 2x-2y-z=2

x+y+z=1 x-2y+3z=2 5x-3y+z=3

Using matrices, solve the following system of equations for x,y and z. 3x-2y+3z=8 , 2x+y-z=1 , 4x-3y+2z=4

Solve x + 2y + z = 8 , 2x - y + z = 3 , x - 2y + 3z = 6 by matrix method

Add the following: (i) x – 3y – 2z , 5x + 7y – 8z , 3x – 2y + 5z

Add the following: (i) x – 3y – 2z , 5x + 7y – 8z , 3x – 2y + 5z

Prove that Det [[x + y + 2z, x, y], [z, y + z + 2x, y], [z, x, z + x + 2y]] = 2 (x + y + z) ^ 3

solve x + 2y + 3z = 8 2x + y + z = 8 x + y + 2z = 6 .

8x + y + 2z = 4x + 2y + z = 1x + y + z = 2
