Therefore Sam collected 42 stamps and Maggie collected 168 stamps
These are made of several equation with unknown variables
Let the amount of stamp Sam be x
Let the amount of stamp Maggie be y
If Maggie has collected four times as many stamps as sam, hence;
y = 4x
If the total stamp is 210, hence;
x + y =210
x + 4x =210
5x = 210
x = 210/5
x = 42
Since y = 4x
y = 4(42)
y = 168
Therefore Sam collected 42 stamps and Maggie collected 168 stamps
