Answer
If Jesse's score on the first day is x
The equation that represents what is described in the question is
x - 6 = 0
x = +6 (6 above par)
Jesse's score on the first day = +6 (6 above par)
Step-by-step explanation
Let Jesse's score on the first day be x
Jesse's score on the second day = -6 (6 below par)
His total score for the two days was 0
So, the sum of his scores for the two days can be written as
x + (-6)
And that is equal to 0
x + (-6) = 0
x - 6 = 0
We can then solve this to obtain x; Jesse's score on the first day
x - 6 = 0
Add 6 to both sides
x - 6 + 6 = 0 + 6
x = +6 (6 above par)
Hope this Helps!!!
