is there any TRICK or ORDER to solve 3x3 elementary ROW
OPERATION problems

Piyush Jain · Accepted Answer

There is no as such trick for solving 3×3 order matrix by
elementary row transformation We just need to keep in mind that,
while converting the main matrix into identity matrix, we shouldnot
disturb the element converted in previous steps So, i am suggesting
you a path, to convert the matrix into identity matrix This path
will enable you toproceed successfully First of all make a11=1,
then a21=0,a31=0,a32=0,a33=1,a23=0, a22=1,a12=0,a13=0
