Answer:
Step-by-step explanation:
Let X is the number of cards Kenny has
Let Y is the number of cards Lee has 
1. Kenny had 5/7 more trading cards than lee, it means
X = Y + 5/7X (1) 
2. After Kenny collected 50% more trading cards, he had 220 more trading cards than lee, it means: 
X + 50%X = Y +  220 (2) 
So, we solve the 2 equations to find out X and Y 
 
 
<=> X =  and Y =
 and Y =  
 
<=> X ≈181 and Y ≈ 52
