Related to the second degree of BACHILLERATO (SENIOR YEAR), we will find the INVERSE MATRIX through its transposed and attached matrix. First, we must find the determinant of the matrix given to prove if it is invertible (its determinant is not null).
CLARIFICATION: when finding the attached matrix, each element must multiply by (-1)^(i+j) in which "i", "j" are the corresponding number to the row and column respectively. For this reason, there is a change in the sign of the elements for which the sum i+j is odd.
The sign is therefore changed to the elements a12,a14,a21,a23,a25,a32,a34...
