দেখাও যে নীচের সমীকরণ তিনটির কোন সমাধান নেই `3x+2y+3z = 2 , 5x+7y+5z = 3, 4x+5y+4z = 4`

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

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

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

Using matrix method examine whether the following system of equations is consistent or inconsistent or has infinite number of solutions: 3x + 2y+ 3z = 2, 5x + 7y + 5z = 3 and 4x + 5y + 4z = 4

Add : 8x - 3y + 7z, -4x + 5y - 4z, -x - y - 2z

The system 2x + 3y + z= 5, 3x + y + 5z =7, x + 4y -2z=3 has

The equations x+2y+3z=1 2x+y+3z=1 5x+5y+9z=4

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