B. $\left[\begin{array}{cc}8& 9\\ 2& 15\end{array}\right]$

C. $\left[\begin{array}{cc}8& 9\\ 2& 3\end{array}\right]$

D. $\left[\begin{array}{cc}8& 7\\ 2& -3\end{array}\right]$

E. $\left[\begin{array}{cc}8& 7\\ 2& 6\end{array}\right]$

Penyelesaian

Diketahui:

$A=\left[\begin{array}{cc}5& 3\\ 2& 6\end{array}\right]$

$B=\left[\begin{array}{cc}4& 4\\ 5& -6\end{array}\right]$

$C=\left[\begin{array}{cc}1& -2\\ 5& -3\end{array}\right]$

Ditanya:A+B-C

jawab

$\left[\begin{array}{cc}5& 3\\ 2& 6\end{array}\right]+\left[\begin{array}{cc}4& 4\\ 5& -6\end{array}\right]-\left[\begin{array}{cc}1& -2\\ 5& -3\end{array}\right]$

$=\left[\begin{array}{cc}(5+4-1)& (3+4-(-2))\\ (2+5-5)& (6+(-6)-(-3))\end{array}\right]$

$=\left[\begin{array}{cc}8& 9\\ 2& 3\end{array}\right]$
