Answers (1)

Answer: $x=2\: and\: y=7$

Hint: We can use the basic union concept of matrices.

Given: if $\begin{bmatrix} x+3 &4 \\ y-4 & x+y \end{bmatrix}=\begin{bmatrix} 5 &4 \\ 3 & 9 \end{bmatrix}$ Find x and y

Solution:

Here,

$x+3=y$

$x=2$ .......(i)

$\therefore y-4=3$

$y=7$ .........(ii)

$\therefore x+y=9$

$=2+7=9$ [From (i) and (ii)]

RHS=LHS

So, $x=2\: and\: y=7$
