We have , from where , and .
I am generally not too bad at rearranging formulas, but the result I have for the below differs from that which my colleague has calculated. Other opinion(s) would be very much appreciated.
If possible a couple of intermediate steps would be useful for my understanding.
The equation is below and I would like to solve for X
When I rearrange i get:
[that is a B by the root sign]
I would very much appreciate another interpretation.
(I hope this is the correct forum I did think about it!)
Thanks very much for the response.
Would it be possible to explain 2 of the steps?:
First step: how does "(y - D)" become the denominator as opposed to just "y"
Last step: How (A - D)/(y - D) becomes (A - y)/(y - D)
i apologise if I am being a bit thick here.
