Given,`[[4 ,2],[ 3, 3]]=[[1, 2 ],[0, 3]][[2 ,0],[ 1 ,1]]`
On using ` C_2 ->
C_2 -2C_1` we get
`[[4 ,2-2.4],[ 3, 3-2.3]]=[[1, 2 ],[0, 3]][[2 ,0-2.2],[ 1 ,1-2.1]]`
=`[[4 ,-6],[ 3, -3]]=[[1, 2 ],[0, 3]][[2 ,-4],[ 1 ,-1]]`
Since, on using elementary column operation on X=AB, we apply these operations simultaneously on X and on the second matrix B of the product AB on RHS.
