Answer

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

Steps

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

Step 2 ：We need to find $A - B$

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

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