2 + 7 = 9
Answer:
First Place wins in 15 events
Second Place wins in 12 events
Step-by-step explanation:
Let
the number of events winning first place be "f"
the number of events winning second place be "s"
Total 27 swimming events, we can write:

First place wins is THREE MORE than 2nd place wins, so we can write:

Replacing 2nd equation in 1st equation, we can solve for "s":

We know
f = s + 3
so,
f = 12 + 3
f = 15
Thus,
<u>First Place wins in 15 events</u>
<u>Second Place wins in 12 events</u>
