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

5x-y=-7 2x+3z=1 3y-z=5

If (x,y,z) is the solution of the equations 4x + y = 7 3y + 4z = 5 5x + 3z = 2 Then the value of x + y + z equals

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

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

The lines x + y + z - 3 = 0 = 2x - y + 5z - 6 and x - y - z + 1 = 0 = 2x + 3y + 7z - k are coplanar then k equals

3x+4y+7z=4, 2x+y+ 3z= 3, x + 2y +3z =8.
