Anna, Ben, and Cindy have M markers together. Anna has A markers, and this is twice as many markers as Ben has. How many markers does Cindy have?
_____ markers
Translate into Algebra.
---------------------------------------------------------- 

Since Anna has A markers, B has A%2F2 markers, according to the condition.

Anna and Ben together have A+%2B+A%2F2  = %283%2F2%29A markers.

So, Cindy has M - %283%2F2%29%2AA markers.

Is everything clear to you?
