Classwork 2

Aaron, Ben and Charles shared 110 marbles. Ben received twice as many marbles as Aaron. Charles received 10 more marbles then Aaron. How many marbles did each boy receive?

Let Aaron marbles be x
Ben = x X 2 = 2x
Charles = x + 10
x + 2x + x + 10 = 4x + 10
4x + 10 = 110
4x = 100
Aaron = x = 25
Ben = 2x = 50
Charles = x + 10 = 35
