If \(\begin{bmatrix}x+y&4\\1+z&y\end{bmatrix}=\begin{bmatrix}2&4\\5&6\end{bmatrix}\), then
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → \(x=-4, y=6,z= 4\)
Equal matrices have equal corresponding entries:
\(y = 6\)
\(1 + z = 5,\quad z = 4\)
\(x + y = 2,\quad x = 2 - 6 = -4\)
