Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have:

AX + X = B, all of them being matrices. I have the numbers in the A and B matrices and I have to find the exact values of a,b,c,d (numbers in the X matrix)

I wanted to check if my method is correct:

I multiplied both sides by A^{-1}.

2X = A^{-1}B

So my values for abcd would be half of the matrix I get when I multiply A^{-1}by B:

Thanks,

Peter G.
