Find the values of \(x\), \(y\) and \(z\) using the matrices given below.
1.\(\begin{bmatrix}
8 & 8\\
x & 8
\end{bmatrix} = \begin{bmatrix}
y & z\\
9 & 8
\end{bmatrix}\)
8 & 8\\
x & 8
\end{bmatrix} = \begin{bmatrix}
y & z\\
9 & 8
\end{bmatrix}\)
Here, \(x\) \(=\) , \(y\) \(=\) and \(z\) \(=\) .
2. \(\begin{bmatrix}
x + y + z\\
x + z\\
y + z
\end{bmatrix} = \begin{bmatrix}
21\\
12\\
15
\end{bmatrix}\)
x + y + z\\
x + z\\
y + z
\end{bmatrix} = \begin{bmatrix}
21\\
12\\
15
\end{bmatrix}\)
Here, \(x\) \(=\) , \(y\) \(=\) and \(z\) \(=\) .
