Thread: solving the matrix equation

Let A =
1 1
0 1
and B =
0 -1
1 0

Solve the following matrix equation for X:
(BA)X^T =
1 0
-1 1

I'm sorry those are suposed to be matrixes. So I know that first I have to find BA which is
0 -1
1 1
Then I know that X^T times BA is
1 0
-1 1
And after that I'm stuck(

Click on those to see the code I used.

If Ax= C then . Since you have already found BA, find its inverse and multiply by .

thank you!
