    Solve for Y

    X = Y+(Y-Z)AB

    What are the steps to simplify this equation and solve for Y?

    Thanks

    hints:

    1) open bracket and keep terms containing y on either side and shift other term another side
    2) take common y from terms containing y
    3) divide both side by (product term of y)

    e.g. in this sum

    X = Y+(Y-Z)AB
    X = Y+YAB-ZAB
    X+ZAB= Y+YAB
    X+ZAB= Y(1+AB)
    divide both side by (1+AB)
    Y= \frac{X+ZAB}{1+AB}

    Bingo! That is awesome!

    I got stuck going from this
    X+ZAB= Y+YAB

    to this
    X+ZAB= Y(1+AB)
