Answer
Fill the blanks with
$1,\ 7,\ 0,\ 14$
Work Step by Step
To add two matrices of the same dimension, add corresponding elements.
Two matrices are equal if they have the same dimension and if corresponding elements, position by position, are equal.
---
Adding the matrices on the LHS, we have
$\left[\begin{array}{ll}
1 & 7\\
0 & 14
\end{array}\right]=\left[\begin{array}{ll}
w & x\\
y & z
\end{array}\right]$
Position by position,
$w=1, x=7, y=0, z=14.$
Fill the blanks with
$1,\ 7,\ 0,\ 14$
