Hi Peleus!
This is a 2x2 matrix and there is a formula for this problem

But you don't want to use this, right?

Hi all,
Quick question.
I'm just unsure of how to handle an unknown in a matrix when talking about finding the inverse.
Usually I simply augment (A|I) and reduce it to RREF and read the inverse off the identity matrix.
This is the matrix however I have to do it on -
Obviously I'm not (in any way I can think of) able to reduce the x to a zero, so how do I transform this into reduced row echelon form, and hence get the inverse?
Cheers.
