Answer: Alice's team
Step-by-step explanation: Add twelve and six you get 18; add 15 and 18 you get 33; now 18- 12= 6 so Alice won 6 games out of 18 so that ratio is 6:12 12-6=6; while Lucy's team's ratio is 15:18, 18- 15= 3. 3 is less than 6 so Alice's team had a higher ratio of wins to loses.
we have the numbers

we know that
The sum of a number and its additive inverse is 0
so

therefore
the number n is equal to 
the sum is equal to zero
