Let's assume that Oscar scored x points. According to the problem, Paul scored 20 points more than twice the number of points Oscar scored. We can write this information as:
Paul's score = 58
Paul's score = 2 * Oscar's score + 20
We can substitute 58 for Paul's score in the second equation and simplify:
58 = 2x + 20
Subtracting 20 from both sides, we get:
38 = 2x
Dividing both sides by 2, we get:
x = 19
Therefore, Oscar scored 19 points. The equation that represents the situation to find how many points Oscar scored is:
2x + 20 = 58
where x is the number of points Oscar scored.
