The solution of `7x+5y-13z+4=0`, `9x+2y+11z= 37`, `3x-y+z=2` is

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

Solve the system: x + y - 2z = 0, 2x - 3y + z = 0, 3x - 7y + 10z = 0, 6x - 9y + 10z = 0.

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

The number of solutions of the system of equations x+y+z = 4, 2x + 5y – 2z = 3 and x + 7y – 7z = 5, is /are a)0 b)1 c)2 d)infinite

Which of the following equations are consistent? If consistent, find their solutions. {:(x - 3y - 8z = -10),(3x + y - 4z = 0),(2x + 5y + 6z = 13):}

The system of equations 4x+y+2z=5, x-5y+3z=10, 9x-3y+7z=20 has

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