[" 9."x-2y=3],[2x-z=3],[3y-4z=7]

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

The values of x, y, z for the equations x-y+z=1, 2x-y=1, 3x+3y-4z=2 are

x-y=3 2x+3y+4z=17 y+2z=7

Solve : x-2y+3z=2 3x+y-z=3 8x-2y+4z=10

The pair of simultaneous equations from the following is…………………(1) 2x+2y=7 (2) 4x+3z=9 (3) 3y+4z=8 (4)3z+9x=18 a)1 and 2 b)2 and 3 c)3 and 4 d)2 and 4

Show that each of the following systems of linear equations is consistent and also find their solutions: 6x+4y=2 9x+6y=3 2x+3y=5 6x+9y=15 5x+3y+7z=4 3x+26 y+2z=9 7x+2y+10 z=5 x-y+z=3 2x+y-z=2 -x-2y+2z=1 x+y+z=6 x+2y+3z=14 x+4y+7z=30 2x+2y-2z=1 4x+4y-z=2 6x+6y+2z=3

The solutioni of x+y+z=7,x+2y+3z=16,x+3y+4z=22 is
