Homework Statement
find all matrices x that satisfy the given matrix equation
[ 1 2 3
4 5 6] * X = I_2
I_2 is the identity matrix 2x2
Homework Equations
The Attempt at a Solution
I just inverted the square matrix
[ 1 2
4 5]
so it becomes
[5 -2
-4 1 ]
so X should be
[ 5 -2
-4 1
0 0]
but my book solution introduces 2 variables S and T to capture all the solutions, how do i do this?
*ps, how do i make my matrices neater?
