MCQ

If $\left[ {\begin{array}{*{20}{c}}x&0\\1&y\end{array}} \right] + \left[ {\begin{array}{*{20}{c}}{ - 2}&1\\3&4\end{array}} \right] = \left[ {\begin{array}{*{20}{c}}3&5\\6&3\end{array}} \right] - \left[ {\begin{array}{*{20}{c}}2&4\\2&1\end{array}} \right]$, then

A
$x = - 3,y = - 2$
✓
$x = 3,y = - 2$
C
$x = 3,y = 2$
D
$x = - 3,y = 2$

✓

Answer

Correct option: B.

$x = 3,y = - 2$

b
(b) Since$x - 2 = 3 - 2 \Rightarrow x = 3$

and $y + 4 = 3 - 1 \Rightarrow y = - 2$.
