**Answer:**

Jay: **22 **

Blair: **11**

**Step-by-step explanation:**

There are 33 fish, since Jay caught 2 times as much as Blair it means Jay has the same amount of fish as Blair times 2.

**Jay's fish = Blair's fish X2**

So it means Jay's fish plus Blair's fish is 3 times the original amount as Blair's.

**Blair's fish + Jay's fish = 33**

So to find Blair's amount of fish, divide 33 by 3. You then get 11, 22 is how much Jay has.

I hope this helped, have a great day :D
