Hi Tae,
Let's use the variable, r , to represent the number of hits that Ricky got.
Then we can write the following expression to represent the number of hits that Pedro got: 285 + r
Since their total was 2677, we can write:
Number of hits for Ricky + Number of hits for Pedro = 2677
285 + r + r = 2677
Now combine like terms and use inverse operations to solve for r:
285 + r + r = 2677
285 + 2r = 2677
285 + 2r - 285 = 2677 - 285
2r = 2392
2r/2 = 2392/2
r = 1196
Ricky got 1196 hits.
Pedro had 1196 + 285 = 1481 hits.
