Answer
The statement is false.
To make it true, replace " ... is an ..."
with
".. is not an..."
Work Step by Step
If $A=\left[\begin{array}{ll}
a & b\\
c & d
\end{array}\right]$, then$ A$ is invertible if and only if $ad-bc\neq 0$.
-----------
$ad-bc=1(3)-(-1)(-3)=3-3=0.$
So, A is not invertible.
The statement is false.
To make it true, replace " ... is an ..."
with
".. is not an..."
