Find the value of (x + y) from the following equation :
\(2\begin{bmatrix}
1& 3 \\[0.3em]
0&\text{x} \\[0.3em]
\end{bmatrix}
\) + \(\begin{bmatrix}
y& 0 \\[0.3em]
1&2 \\[0.3em]
\end{bmatrix}
\) = \(\begin{bmatrix}
5& 6 \\[0.3em]
1&8 \\[0.3em]
\end{bmatrix}
\)
2[(1,3)(0,x)] + [(y,0)(1,2)] = [(5,6)(1,8)]
