You can put this solution on YOUR website!
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%28+2%2C+3%2C+4%2C-6%2C54%2C+20%2C-30%2C+270%29 R2 -5R1 --> R2
matrix%28+2%2C+3%2C+4%2C+-6%2C54%2C+0%2C+0%2C+0%29
Since the second row is all 0s, that equation must be the 'same as' the first row. Answer, no can do :)
