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

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

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

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

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

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

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

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

The solution of 2x+y+z=1,x-2y-3z=1,3x+2y+4z=5 is
