Let x = the number of marbles for Phil
Then 3x = the number of marbles for Peter
Together they have 3x+x=48 or 4x=48 and x=12
So Phil has x = 12 marbles and Peter has 3x, let x = 12, 3(12) = 36 marbles.
Peter has 24 more marbles than Phil.

Actually Peter has 24 more marbles than Phil. This is because Phil has 12 marbles, and the difference between 12 and 36 is 24.

It's not asking for the difference. How does 24 +12=48?
More means addition.
