Problem 1
k = Kevin's score
7k = seven times Kevin's score
7k-13 = thirteen fewer than the previous amount = Jason's score of 50
7k-13 = 50
7k = 50+13
7k = 63
k = 63/7
k = 9
Answer: Kevin scored 9 points
================================================
Problem 2
p = number of goals Paul scored
6p = six times the previous unknown number
6p-8 = eight fewer than the previous number = Ken's goal count (22)
6p-8 = 22
6p = 22+8
6p = 30
p = 30/6
p = 5
Answer: Paul scored 5 goals
