Homework Statement

in this question , solving equation 1 and 2 , how to get the
F1 = (A1E1 P ) / ( 2A1E1 + A2E2) ? and also F2 ?

Homework Equations

The Attempt at a Solution

we know that F2 = P -2F1 )
I have tried to sub (F2 / A2E2 ) in F1 = (A1E1 P ) / ( 2A1E1 + A2E2) , but i ended up getting (A1E1P - 3 F1A1E1 ) / A2E2 , which is not same as the author , did i miss out any equation ? [/B]

Hi Chetz,

It's a lot easier: substitute [2] in [1] and there you are !
