Linear algebra question: Solve the system of equations DCx = 0 C=[2, -1] .....[ 1, 1] .....[ 2, 1] D=[ 0, 2] .....[-1,3] So, I have my product DC i got from matrix multiplication, it is: .......[5,-1] DC=[2, 2] ........[1, 4] So now I'm not sure where to go.... They don't even say if its a vector, matrix, scalar....? Do I just divide both sides by DC and get x=0? Thanks for any help you give.

You cant divide matrices with other matrices, you would have to look for another way to solve that. A hint: Identity Matrix. :)
