Question

Using the matrix method for the three-number system, what are \[x,y,z\]?

पर्याय

• \[x=1,\ y=2,\ z=3\]

• \[x=3,\ y=2,\ z=1\]

• \[x=2,\ y=1,\ z=3\]

• \[x=1,\ y=3,\ z=2\]

Answer 1

Matrix multiplication gives \[X=\frac19\begin{bmatrix}9\\18\\27\end{bmatrix}=\begin{bmatrix}1\\2\\3\end{bmatrix}.\] Hence, the first, second, and third numbers are \(1,2,3\), respectively.
