4x + 3y + 2z =1 x-y + 3z = 4 2x + 5y - 4z = 6 has n solution than n = | CLASS 12 | MOCK TEST 3 ...

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

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

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

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

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

3x+4y+7z=4, 2x+y+ 3z= 3, x + 2y +3z =8.

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
