a az a3 11 Change the matrix a4 as a 0 to the reduced row echelon form, where as ag 0 a7 a, az, az, a4, as, a6, a7, ag, and a, are the nine digits of your ID from left to right. (Example: if your ID is 214110008, then the coefficients are: a = 2, a = 1, a3 = 4,a = 1, a5 = 1,a6 = 0, a, = 0, ag = 0, and ag = 8.) a Change the matrix a4 a7 a, az, az, a4,as, a6, a7, ag, and a, are the nine digits of your ID from left to right.
