In the sets of equations `z^x =y^(2x)`, `2^z = 2. 4^x`, x+y+z = 16 , the integral roots in the order x, y, z are :

If the set of equations z^x=y^(2x) , 2^z=2*4^x , x+y+z=16 , the integral roots in the order x , y , z are: a.    3 , 4 , 9 b.    9 , -5 , 12 c.    12 , -5 , 9 d.    4 , 3 , 9

If the sets of equations z^(x)=y^(2x),2^(x)=2.4^(x),x+y+z=16, the integral roots in the order x,y,z

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

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

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

Examine the consistency of the system of equations x + y + z = 1 2x + 3y + 2z = 2 a x + a y + 2a z = 4

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

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

2x-3y+5z=16, 3x+ 2y-4z= -4, x + y - 2z =- 3.
