Question

find the value of x and y​

Answer 1

Answer:

y=10,x=2

Step-by-step explanation:

$2\begin{bmatrix}x&7\\ 9&y-5\end{bmatrix} + \begin{bmatrix}6&-7\\ 4&5\end{bmatrix}=\begin{bmatrix}10&7\\ 22&15\end{bmatrix}\\\\\\\implies \begin{bmatrix}2x&14\\ 18&2\left(y-5\right)\end{bmatrix}+\begin{bmatrix}6&-7\\ 4&5\end{bmatrix}=\begin{bmatrix}10&7\\ 22&15\end{bmatrix}\\\\\\\implies\begin{bmatrix}2x+6&7\\ 22&2y-5\end{bmatrix}=\begin{bmatrix}10&7\\ 22&15\end{bmatrix}\\\\\\\implies\begin{bmatrix}2x+6=10\\ 2y-5=15\end{bmatrix}\\\\\\\implies y=10,\:x=2$
