Hi i'm studying linear algebra, first of all sorry for screen shots if it's not a good idea but I don't know how to write a matrix in StackExchange.
So question gave me A Matrix and I have to find its inverse so I got the inverse :
And Now I have to solve this "A.X = B" :
I'm not sure how I should solve this, should I Multiply Matrix A inverse with 4-vector column Matrix B ? to find Matrix X ?
