Let's use the information provided to set up an equation.
- Let \( x \) be the number of video games in Matthew's collection.
- The number of video games in Anthony's collection is \( 5x \).
- The total number of video games in both collections is 72.
We can express this relationship with the equation:
\[ x + 5x = 72 \]
Now, combine like terms:
\[ 6x = 72 \]
Next, we solve for \( x \):
\[ x = \frac{72}{6} = 12 \]
Therefore, the number of video games in Matthew’s collection is \( \boxed{12} \).
