2x+3y+4z" by "9x

The system of linear equations x - 2y + z = 4 2x + 3y - 4z = 1 x - 9y + (2a + 3)z = 5a + 1 has infinitely many solution for:

The system of linear equations x - 2y + z = 4 2x + 3y - 4z = 1 x - 9y + (2a + 3)z = 5a + 1 has infinitely many solution for:

The following system of linear equations 2x + 3y + 2z = 9 3x + 2y + 2z = 9 x - y + 4z = 8

If the equation of the sphere through the circle x ^(2) +y ^(2) + z ^(2) = 9, 2x + 3y + 4z = 5 and through the point (1,2,3) is 3 (x ^(2) + y ^(2) + z ^(2)) - 2x - 3y - 4z = C, then the value of C is

2x = 3y = 4z, x: y: z

Solve the following set of equations 2x+3y -z = 9; x +y +z = 9; 3x - y - z = -1 .

Solve the equations x-y+3z=10,x-y-z=-2 and 2x+3y+4z=4 by matrix method.
