It is a.
is it 4 inverse of mod 17 or whole inverse? Whole inverse do not make sence, so, ans for the q is 13.
Usually there is an inverse key or( tan -1 )key for this
The answer depends on what you mean by "opposite": whether it is the additive inverse or the multiplicative inverse.
it is used to find the inverse of the matrix. inverse(A)= (adj A)/ mod det A
You can factorize the matrix using LU or LDLT factorization algorithm. inverse of a diagonal matrix (D) is really simple. To find the inverse of L, which is a lower triangular matrix, you can find the answer in this link.www.mcs.csueastbay.edu/~malek/TeX/Triangle.pdfSince (A T )-1 = (A-1 )T for all matrix, you'll just have to find inverse of L and D.

The fact that the matrix does not have an inverse does not necessarily mean that none of the variables can be found.
