I'll go out on a limb and suppose you're given the matrix

and you're asked to find the determinant of

, where

and given that

.

(1) Whenever a single row/column is scaled by a constant

, then the determinant of the matrix is scaled by that same constant;
(2) Adding/subtracting rows does not change the value of the determinant.
Taken together, we have that
