    Algebra on CVP Analysis

    Hi Guys,

    Algebra has never been one of my academic strong points and whilst I understand the basics I'm having trouble understanding the workings of the following calculation. So yes I do have the answer but I just don't get how the final result was reached, any assistance would really be appreciated:

    P = SX-VF-F (No need to drill down here, I understand the CVP formulae)
    For this particular equation though the workings were revealed as follows:

    10% of 2.5x = 2.5x - 2x - 800
    x = 3200

    Feedback would be appreciated.

    (10% of 2.5x) = 2.5x - 2x - 800

    0.25x = 2.5x - 2x - 800

    0.25x = (2.5x - 2x) - 800

    0.25x = 0.5x - 800

    0.25x - 0.5x = -800

    (0.25x - 0.5x) = -800

    -0.25x = -800

    x = (-800)/(-0.25) = 800*4 = 3200

    Basic Operations. One at a time.

    Thank you TK, the expanded workings make a great deal more sense.

    Really appreciate it.
