Asked by Chris

Sam had a total of 80 foreign stamps and local stamps combined. After giving away 1/3 of his foreign stamps and 10 local stamps, he had an equal number of foreign stamps and local stamps left. How many local stamps did he have in the beginning?
Answered by Steve
f+l = 80
2/3 f = l-10

so,

2/3(80-l) = l - 10
160-2l = 3l-30
190 = 5l
l = 38

check:
initially there were
38 local and 42 foreign
after removing 10 local and 14 foreign, there were 28 of each.

Where do you get 2/3rds from
Answered by Answerer
The 2/3rds come from how much is left after 2/3rds are gone.
