The correct answer is: x=4, y=-3, z=2

It is given that

223711065xyz=3y+116z-15y+11+xx4z+z3x4y

Solve the above matrix

2x+2y+3z7x+y+z6y+5z=3y+x+z+113x+x+6z-15y+4y+4z+11

2x+2y+3z7x+y+z6y+5z=x+3y+z+114x+6z-19y+4z+11

On comparing
x-y+2 z=11

3x+y-5z=-1

-3 y+z=11

From the above three equations

x=4, y=-3, z=2
