By the given information you can raise the following equation, and since levon scored 38 points in the first half of the basketball game, then
![\begin{gathered} TP=38+n \\ \text{Where} \\ TP\colon\text{ the number of points that he scored in total.} \\ n\colon\text{ the number of points that he scored in the second half of the game} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/wyz3capv8ht7i6ukl0dzprcoc4ktnbd26a.png)
So, if n=20
![\begin{gathered} TP=38+n \\ TP=38+20 \\ TP=58 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/h7c26e635phba8qcr8gbs8mh1dv1hvvw7d.png)
Therefore, if Levon scored 20 points in the second half of the game, in all he scored 58 points.
