Answer

$\boxed{A-B=\left[\begin{array}{cc}-14 & 2 \ -7 & 8\end{array}\right]}$

Steps

Step 1 ：Let $A=\left[\begin{array}{cc}-7 & 2 \ -3 & 5\end{array}\right]$ and $B=\left[\begin{array}{cc}7 & 0 \ 4 & -3\end{array}\right]$

Step 2 ：We need to find $A-B$

Step 3 ：Subtracting the corresponding elements in matrices A and B, we get $A-B=\left[\begin{array}{cc}-14 & 2 \ -7 & 8\end{array}\right]$

Step 4 ：$\boxed{A-B=\left[\begin{array}{cc}-14 & 2 \ -7 & 8\end{array}\right]}$
