LinearAlgebra Package / stdlib Question on rhs variables

Hi all,

I want to know whether with Julia we can use the right hand side as variables (b1, b2, b3) and it can still be calculated as its variables multiplication after doing the elementary row operations on the matrix?

We can use the calculation with all constants, it can compute directly the result. I type this, and have no idea whether we can code this, so I can change the matrix A and see the right hand side(rhs) in terms of variables b1,b2, and b3.

You want Symbolic Calculations and Building Callable Functions · Symbolics.jl, probably. The linked page has some good examples.
