Question

\frac{ 1 }{ 3 }*X*A+I _{2}=A ^{T}
How do I proceed with this?

Answer 1

Are those matrices? are you solving for X?

Answer 2

Yup

Answer 3

\[\frac{ 1 }{ 3 }*X*A+I _{2}=A ^{T}\]

Answer 4

what is A?

Answer 5

\[\left[\begin{matrix}3 & 6\\ 1& 3\end{matrix}\right]\]

Answer 6

Would it be right to write it like this:
\[X=(3A ^{T}-3I _{2})A ^{-1}\]

Answer 7

yeah

Answer 8

and then like this:
\[X=3A ^{T}A ^{-1}-3I _{2}A ^{-1}\]

Answer 9

yeah, i think so, you know A so you can work out the right hand side,

Answer 10

Yup, I'll give it a try ;)
Thanks!

Answer 11
