Kim, Mei and yante collect stamps. Kim and Mei have 220 stamps more than Yanti. Yanti and Mei have 140 stamps more than Kim. Kim and Yanti have 500 stamps. How many stamps does Mei have?

Answer 1

k+y = 500
k+m = y+220
y+m = k+140

Or, in more standard format,
k+m = 500
k+m-y = 220
-k+m+y = 140

These are easy to solve.
