Answer:
22
Step-by-step explanation:
Let W be the number of winner points and L be the number of loser points. The total number of points is 22 + 13 = 35. Total number of win points + total number of loser points = 35. So W + L = 35. The difference between the total number of winner points and loser points is 22 - 13 = 9. So, W - L = 9. Now we have two simultaneous equations.
W + L = 35
W - L = 9 adding the two equations, we have
2W = 44
W = 44/2 = 22
