Question: I need 2 3x3 matrix determinants for a circuit's equation

I am trying to determine the mesh current method using a circuit that I have constructed using OrCad the similator has the correct voltages and currents but I am having difficulty with Maple getting the 2 matrixs to come out properly. The method is called the cramer method. I am using it in conjunction with a 2 voltage source circuit.... Matrix one is to be divided by Matrix 2

Matrix one is

40   -8   0

0     20   -6

-20   -6    10

__________

Matrix 2 is

10   -8   0

-8   20   -6

0    -6    10

 

the answer is 5.6, but how do I set up so that maple will divide the two 3 x 3 matrixs
