Find the values of x, y and z from the following equations
(i) \(\begin{bmatrix}
12&3 \\[0.3em]
x & \frac{3}{2} \\[0.3em]
\end{bmatrix}\)= \(\begin{bmatrix}
y&z \\[0.3em]
3& 5\\[0.3em]
\end{bmatrix}\)
(ii) \(\begin{bmatrix}
x+y&2 \\[0.3em]
5+z & xy\\[0.3em]
\end{bmatrix}\)= \(\begin{bmatrix}
6&2 \\[0.3em]
5 & 8 \\[0.3em]
\end{bmatrix}\)
(iii) \(\begin{bmatrix}
x+y+z \\
x+z \\y+z
\end{bmatrix}\)= \(\begin{bmatrix}
9 \\
5 \\7
\end{bmatrix}\)
