$$
\text { System } \quad \text { Matrix equation }
$$
$$
\begin{array}{l}{5 x+3 y=4} \quad {A \quad \cdot \quad X \quad=\quad B}\\ {3 x+2 y=3}\end{array}
$$
$\quad\quad\quad\quad\quad\quad[--]\quad[--]\quad=[--]$
(b) The inverse of $A$ is $A^{-1}=$ [_____]
(c) The solution of the matrix equation is $X=A^{-1} B$
$$
X=\quad A^{-1} \quad B
$$
$$
\left[\begin{array}{l}{x} \\ {y}\end{array}\right]={[--]\quad[--]=[--]}
$$
