Dynamics question related to conservation of string

  1. Feb 2, 2017 #1
    1. The problem statement, all variables and given/known data

    2. Relevant equations
    I have a problem understanding this problem. It asks for the velocity of block A when block B is moved 300mm/s to the right. The equation for the cord lenght is given as 2xb-3xa=constant.

    3. The attempt at a solution
    I dont understand the equation at all. wouldnt the total cord of the lenght be xb + (xb-xa) +2xa= constant? help!! i understand how to get velocities and all the problems similar to this one, but expect this one :(
