i have another one To calculate the determinant of the following matrix, I would like to ask is it possible to eliminate any lines,because I don't see how.. and calculating the determinant without elimination is kinda painful.

Of course! I would recommend cofactor expansion along (row or column) (3 or 4). This will leave only two 3x3 determinants to calculate.
