equations involving variatbles has column vectors
C_1 x1 + C2 x2 … = b
or where x is the col vector of unknowns A is the matrix of col vectors
There are three ways to solve it.
matrix inverse
this is smply x = A-1 b
but this needs the inverse and is mainly for the good case of n equations n vars.
guassian elimination
Aug = [ A | b] convert to echelon form
