If $\text{DEVICE}$ is coded as $\text{BAREXA}$ and $\text{ORNATE}$ is coded as $\text{ZVMESA}$, what will $\text{VIDEO}$ be coded as?

Let's extract the direct substitution code for each letter from the given words:
From $\text{D-E-V-I-C-E}\to \text{B-A-R-E-X-A}$:

* $\text{D}\to \text{B}$
* $\text{E}\to \text{A}$
* $\text{V}\to \text{R}$
* $\text{I}\to \text{E}$
* $\text{C}\to \text{X}$

From $\text{O-R-N-A-T-E}\to \text{Z-V-M-E-S-A}$:

* $\text{O}\to \text{Z}$
* $\text{R}\to \text{V}$
* $\text{N}\to \text{M}$
* $\text{A}\to \text{E}$
* $\text{T}\to \text{S}$

Now let's map the letters of the word $\text{VIDEO}$:

* $\text{V}\to \text{R}$
* $\text{I}\to \text{E}$
* $\text{D}\to \text{B}$
* $\text{E}\to \text{A}$
* $\text{O}\to \text{Z}$

Combining these gives $\text{REBAZ}$.
