We start with the equation given:
\[ 4y = 104x \]
To find the average points per game that Pedro scored, we need to solve for \( y \) (the total points scored) in terms of \( x \) (the number of games). We can rearrange the equation as follows:
\[ y = \frac{104x}{4} \]
Simplifying the right side gives:
\[ y = 26x \]
Now, to find the average points per game, we need to find \( \frac{y}{x} \):
\[ \frac{y}{x} = \frac{26x}{x} = 26 \]
Thus, Pedro scored an average of 26 points per game.
