Question 125589
First create the coefficient matrix, which is just a matrix of the coefficients on the variables.


{{{(matrix(2,2,3,2,1,-3))}}}


Then add a new column consisting of the constant terms


{{{(matrix(2,3,3,2,7,1,-3,17))}}}, Done.


Generally, the symbols are large square brackets around the outside of the matrix and a vertical line separating the new column from the original coefficent entries, but this formula rendering scheme doesn't allow me to show it that way.
