The inverse of the matrix is the matrix .
The inverse of a matrix A is calculated by the formula:
A' = (1/|A|)(Adj A),
where A' represents the inverse of matrix A,
|A| represents the determinant value of matrix A, and
Adj A represents the Adjoin matrix of matrix A.
So, to calculate the inverse of the matrix , we will first calculate its Adj.
Adj = = .
Now, we calculate |A| = 11*(-1) - (-5)*3 = -11 + 15 = 4.
Therefore A' = (1/|A|)(Adj A),
or, A' = ,
or, A' = .
Therefore, the inverse of the matrix is the matrix .

You divide -6 and -3
Because the exponents are both negative, you make them positive and change the position (the exponent which is at the denominator is now at the numerator and viceversa)
You divide the exponents (so 2-1)
2*10 = 20
