Which matrix is equal to c-b

Answer:
C - B = [tex]\begin{bmatrix}7 & -20\\ 10 & 3\\ 6 & 3\end{bmatrix}[/tex]
Step-by-step explanation:
The given matrices are B = [tex]\begin{bmatrix}2 & 14\\ -6 & 5\\ 4 & 9\end{bmatrix}[/tex] and C = [tex]\begin{bmatrix}9 & -6\\ 4 & 8\\ 10 & 12\end{bmatrix}[/tex]
Now we have to find C - B
To find C - B we will subtract each row of B from each row of C.
C - B = [tex]\begin{bmatrix}(9-2) & (-6-14)\\ (4+6) & (8-5))\\ (10-4)& (12-9)\end{bmatrix}[/tex]
= [tex]\begin{bmatrix}7 & -20\\ 10 & 3\\ 6 & 3\end{bmatrix}[/tex]
