Hello,

I'm asked to solve for X

I have; AX = 2X + C

$\displaystyle A =

\begin{matrix} 3 & -1 \\ 1 & 2 \\

\end{matrix}

$

$\displaystyle C =

\begin{matrix}

1 & 2 & 0 \\

0 &-1 & 1 \\

\end{matrix}

$

I have an answer but it looks wrong (not very attractive numbers)

What I've done is solve for X

X = C /(A-2) or X=-0.5 (A^-1)(C)

but I think here is where I am going wrong, I also calculated the determinant of A and adj(A) to find the inverse but my numbers are like 0.286 0.143 etc

any help would be appreciated

EDIT: Sorry the matrix messed up in Latex but its still visible
