Hi,

I have been following a tutorial that says to solve systems of linear equations like so:

	Solve[{2x + 4y == -4, 5x + 7y == 11}, {x, y}]

I am wondering if there is a shorthand way to do it by just entering the co-efficients of each equation, i.e. matrix style:

	Solve??[{2,4,-4},{5,7,11}]

cheers,

Ben C.
