Question 466167
{{{(matrix(2,3, -8,-4,-32,2,1,8))}}}
~ {{{(matrix(2,3, 2,1,8,2,1,8))}}}, after -R1/4.

~{{{(matrix(2,3, 2,1,8,0,0,0))}}}, after -R1 + R2

~{{{(matrix(2,3, 1,1/2,4,0,0,0))}}}, after R1/2

The matrix is in reduced row echelon form.  This says that the system is dependent, and the solution set is {(x, y)| x + y/2 = 4}.
