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.
