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

I have a simple problem

consider two matrix equations

A1X=B1

A2X=B2

A1 and A2 are 3X3 matrix. Moreover, A2 is a positive, definite, symmetric matrix. B1 and B2 are two 3X1 column vectors. The A1, A2, B1, B2 are known. I need to find unique solution of X vector from these two equations. Is there any suitable way to do that?

Can I do it by using Lagrange multiplier? It is not a homework problem. I am struggling this by two days but didn't get success.

Thanks in advance

Best
