Hello, thank you for taking the time to post your question!
The general form of the Matrix that you have here is
A – XB = I
So to solve this equation for the value of X you would want to start by rearranging the equation to isolate the value of X
A = I + XB
A – I = XB
In Matrix algebra then rather than dividing you want to multiply by the inverse … so this becomes
(A – I) * inv(B) = X
When I solve that using MATLAB for this expression I get
X = [-1, 0; 4/17, 7/17]
I hope that helps get you moving in the right direction! Feel free to reach out if you have any additional questions beyond that :)
