Hi
How does one tell R that one is using an augmented matrix as appose to an
non-augmented matrix?
Explicitly creating an augmented matrix is unnecessary and
awkward if the object is to solve a system of linear equations.
See:

For instance, when I want to solve two equations in two unknowns, I will
have to solve a 2 by 3 augmented matrix, however all I know to type into R
is something like this;
weights = c(1,2,3,4,5,6) (say)
M1=matrix(weights,ncol=3).
Does R correctly interpret me when I write the above code?
Furthermore, how do I reduce this augmented matrix in R such that it will
give me my two unknown variables?
Thanks so much.
