What are you trying to do? inverse or factor or something like that?
Ok, so:
To do this problem, first, we assign variables.
Let x be the smaps that Many collected.
If Margie collegted 4 times as many stamps as Sam, Margie collected 4x stamps.
Then, we know that both of them have 210.
So x + 4x = 210.
Solving the equation:
5x = 210
And x = 42.
Many collected 42 stamps.
Now, we use the last fact to find how many stamps Margie collected.
Margie collected 4x stamps, that is 4(42), which is equal to 168 stamps.
Margie collected 168 stamps.
