Question

$Find a 2*2 matrix X such that \left[\begin{array}{ccc}5&-7\\-2&3\end{array}\right] X= \left[\begin{array}{ccc}-16&-6\\7&2\end{array}\right]$

Answer 1

Dear Student:

AX=B

$A=\left[\begin{array}{ccc}5&-7&\\-2&3\end{array}\right]$

$B=\left[\begin{array}{ccc}-16&-6&\\7&2\end{array}\right]$
