To find the equation that relates Lee's score to Alex's score, we can start with the information given:
- Lee scored 25 points.
- This was 3 more than twice the number of points Alex scored.
We can let \( a \) represent the number of points Alex scored. According to the problem, we can express this relationship with the following equation:
\[ 25 = 2a + 3 \]
This equation states that Lee's score (25) is equal to twice Alex's score (\( 2a \)) plus 3. This is the equation you can use to find the number of points Alex scored.
