Mathematics - Matrices Question with Solution | TestHub

Since, $A\left[\begin{array}{l}x\\ y\\ z\end{array}\right]=\left[\begin{array}{l}1\\ 0\\ 0\end{array}\right]$ is linear equation in three variables and that could have only unique, no solution or infinitely many solution. $\therefore$ It is not possible to have two solutions. Hence, number of matrices $A$ is zero.
