Step-by-step explanation:
Let :
Amy's stamp = 2437
Maria's stamps = 1347
Let Number of stamps Amy gave to Maria = x
After Giving stamps to Maria ; we have the equation :
Amy's stamps = 2437 - x
Maria's stamps = 1347 + x
(1347 + x) = 3(2437 - x)
1347 + x = 7311 - 3x
x + 3x = 7311 - 1347
4x = 5964
x = 5964 / 4
x = 1491
Number of stamps Amy has in the end :
2437 - 1491 = 946
