hi barandaman
That last line is not quite correct.
Your pi terms have lost their denominator.
Put that in and you can cancel it throughout. The expression is then much simpler.

I really am having trouble with the latex...
The pi terms are different, one is pi^e one is pi^*

]]>That is okay.
Use
]]>It is the problem we looked at yesterday, to solve it we set PI=PI^e, so all that changes is the LHS term is PI^e.
Then I expand the RHS as seen, and get the result as shown initially in the first image. I have no idea how to convert that into the solution, which is:
Pi^e = Pi^* + (b/a)(y^* - ybar)
I hope this is clearer!
]]>Didn't see your post as I was taking a long time over mine.
Bob
]]>here's the LHS using Latex.
I think you need to do two things.
(i) tell us what the question asks
(ii) show how you got this far.
Please use Latex:
You start with square brackets math and end with square brackets /math
The code for the above is:
There is a code for the line over the y but I forget at the moment. But ybar is clear I think.

]]>See if you can write the problem out larger too.
]]>What have you done so far?
]]>Hi,
Could someone please help me with this problem?
I have done some of the deriving up to this point, so if we cannot move from the LHS to the RHS on the attached image, I have done something wrong up to this point and then I will take another photo to show the previous steps, but I really think they were right as it was much more simple.
So we have to get from the LHS to the RHS, dividing by a gives the first two terms, but then I really do not understand how the LAST term on the RHS becomes b/a. Could anyone shed some insight? Thank you so much! Image attached.
