$= 5 x + 76$

#### Explanation:

First decide who has the smallest number of CD's.

Victor has more than Ariel, who has more than Tiffany.
Let the number of Tiffany's CD's be $x$

Tiffany has $x$ CDs

Ariel has $19 \text{ more } \rightarrow x + 19$

Victor has 3 times as many ans Victor:

$3 \left(x + 19\right) = 3 x + 57$

The number od CDs they have together is:

$x + x + 19 + 3 x + 57$

$= 5 x + 76$
