Test the consistency `2x - 3y + 7z = 5 , 3x + y - 3z = 13 , 2x + 19 y - 47 z = 32`

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

Add 2x - 3y + z , 5y - x + 7z and 3x - y - 6z.

If we represent the linear equations x + y - z = 3, 2x + 3y + z = 10 and 3x - y - 7z = 1 in matrix form as AX = B, then A^(T) is:

If the system of equations 2x 3y – z = 5 x alpha y 3z = –4 3x – y beta z = 7 has infinitely many solutions, then 13 alpha beta is equal to

2x + 3y-5z = 7, x + y + z = 6,3x-4y + 2z = 1, then x =

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

Examine the consistency of the system of equations 5x -y + 4z = 5," " 2x + 3y + 5z = 2," " 5x -2y + 6z = 1

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