[" (iv) "4x-5y-2z=2],[2x+2y+8z=-1],[5x-4y+2z=-2]

Show that following system of linear equations is inconsistent: 4x-5y-2z=2,\ \ 5x-4y+2z=-2,\ \ 2x+2y+8z=-1

Show that following system of linear equations is inconsistent: 4x-5y-2z=2,\ \ 5x-4y+2z=-2,\ \ 2x+2y+8z=-1

2x+y+z=1x-y+2z=-1,3x+2y-z=4

4x -5y-11z=12,. x-3y+z=1 2x + 3y-7z = 2

2x-3y+5z=16, 3x+ 2y-4z= -4, x + y - 2z =- 3.

x+2y-2z=5,3x-y+z=8,x+y-z=4

By Matrix inverse method, solve 3x+4y+5z = 18, 2x-y+8z=13, 5x-2y+7z = 20 .

If (x,y,z) is the solution of the equations x - y - 2z = 3 2x + y + 4z = 5 4x - y - 2z = 11 then the value ofy equals
