The solutiion of `(x,y,z)` the equation `[(-1,0,1),(-1,1,0),(0,-1,1)][(x),(y),(z)]=[(1),(1),(2)]` is `(x,y,z)`A. (1,1,1)B. (0,-1,2)C. (-1,2,2)D. (-1, 0, 2) |

Answer» Correct Answer - D `[{:(1,0,1),(-1,1,0),(0,-1,1):}][{:(x),(y),(z):}]=[{:(1),(1),(2):}]` `[{:(x,+0y,z),(-x,1,0z),(0x,-y,+z):}]=[{:(1),(1),(2):}]` `rArr x+z=1` `-x+y=1` and `-y+z=2` On solving these equations, we get `x=-1,y=0,z=2` |
