(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

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

2. Relevant equations

3. 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?
