Dividing Matrices
To divide matrices multiply by the inverse of a matrix. You start by inversing the second matrix. So for a 2x2 matrix you would start by swapping the first and last numbers and putting negatives in front of the second and third numbers​. you then have to divide every by the determinant. To find the determinant, what you have to do is to take the first and last entries multiply them together and subtract the second and third entries multiplied together as well​. Now for the last step, all you have to do it to divide every entry by that number and you will have your answer.
