Question 162478
Create a matrix and then use the G-J method to reduce it. See --> http://www2.krellinst.org/AiS/textbook/unit2/example_projects/starter/math/matrix/gauss.html

{{{ matrix( 2, 3, 4,-6,54, 20,-30, 270)}}} R2 -5R1 --> R2
{{{matrix( 2, 3, 4, -6,54, 0, 0, 0)}}} 

Since the second row is all 0s, that equation must be the 'same as' the first row. Answer, no can do :)
