x+y+z=6.
x-y+z=2
2x+y-z=1

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

x+y+z=4 2x-y+z=-1 2x+y-3z=-9

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

2x-y+z=6,x+2y+3z=3,3x+y-z=4

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

Add 2x - 3y + z , 5y - x + 7z and 3x - y - 6z.

2x + 3y-5z = 7, x + y + z = 6,3x-4y + 2z = 1, then x =

The augmented matrix of x+y+z=6, 2x-y+z=3, 2y-z+x=2 is

What should be added to x y+y z+z x to get x y-y z-z x ? -2x y-2y z-2z x (b) -3x y-y z-z x -3x y-3y z-3z x (d) 2x y+2y z+2z x
