My book doesn't solve it like a linear equation, they solve it by using inverse matrices.

Solve the matrix equation:

|4 -5||m|=|32|

|1 2| |n|=|-5|

A= |4 -5|

|1 2|

X= |m|

|n|

B= |32|

|-5|

Step 1. Find the inverse of the coefficient matrix.

A^-1= 1/13|2 5|

|-1 4|

(I get confused in step 2)

Step 2. Multiply each side of the matrix by the inverse matrix
