If $\begin{bmatrix}2&\text{amp; }3\\4&\text{amp; }4\end{bmatrix}+\begin{bmatrix}\text{x}&\text{amp; }3\\\text{y}&\text{amp; }1\end{bmatrix}=\begin{bmatrix}10&\text{amp; }6\\8&\text{amp; }5\end{bmatrix}$ then $(\text{x, y})=$
  • A
    $(4, 8)$
  • ✓
    $(8, 4)$
  • C
    $(1, 2)$
  • D
    $(2, 4)$
✓

Answer

Correct option: B.
$(8, 4)$
$2 + x = 10$ or $x = 8$
$4 + y = 8$ or $y = 4$
