    Re-arranging

    I am trying to find voltages in a circuit using KVL and KCL and have got these equations:

    1. (x-v)A + (x)B + (x-y)C = 0
    2. (y-v)D + (y-x)C + (y)E = 0

    I need to re-arrange them to get the form:

    1. x(A+B+B) + y(-C) = vA
    2. x(-C) + y(D+C+E) = vD

    But don't know the process.
    I can get the firtst 2 equations from the beginning problem, and given the 2 re-arranged equations I can solve it, but i'm missing a step.Can anyone help?

    1.
    (x - v)A + (x)B + (x - y)C = 0

    xA - vA + xB + xC - yC = 0

    (xA + xB + xC) - yC = vA

    x(A + B + C) + yC = vA

    The second equation is done in a similar manner.
