Best ResponseYou've already chosen the best response.0yes that is correct, however, thats a lil complicated how you've done it.

Best ResponseYou've already chosen the best response.0oh wait, you have just used the inverse formula, i see.

Best ResponseYou've already chosen the best response.0i wouldn't leave it in this form , i would simplify this further

Best ResponseYou've already chosen the best response.0because a solution to the system involves values for x and y, here you have just simply solved the inverse.

Best ResponseYou've already chosen the best response.0i would simplify it further \[X=\left[\begin{matrix}2 & 1/2 \\ 1 & 1/2\end{matrix}\right]\left(\begin{matrix}3 \\ 2\end{matrix}\right)=\left(\begin{matrix}5 \\ 2\end{matrix}\right)\]

Best ResponseYou've already chosen the best response.0here, this simplification says that the solution to this system is x=5, y=2

Best ResponseYou've already chosen the best response.0so you don't get confused, \[X=\left(\begin{matrix}x \\ y\end{matrix}\right)=\left(\begin{matrix}5 \\ 2\end{matrix}\right)\]

Best ResponseYou've already chosen the best response.0im not sure if you could see the first part of it but theres a 1/2 in fornt of it

Best ResponseYou've already chosen the best response.0i did, i just simplified it into the matrix

Best ResponseYou've already chosen the best response.0\[\left[\begin{matrix}2 & 1/2 \\ 1& 1/2\end{matrix}\right]=\frac{ 1 }{ 2 }\left[\begin{matrix}4 & 1 \\ 2 & 1\end{matrix}\right]\]
