In the following matrix equation, the value of x is :
$\begin{bmatrix} x+y & 4\\-5 & 3y \end{bmatrix}=\begin{bmatrix}3 & 4\\-5 & 6\end{bmatrix}$
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 1
comparing corresponding values of matrix
$x+y=3$
$3y=6$
$⇒y=2$
so $x+2=3⇒x=1$
