Algebraic Derivations for Expressions

Please see the attached sheet with 4 equations.
From these 4 equations, I am to get expressions for B/A and C/A. The hint I get is to express F and G in terms of C from the last 2 equations, and use this to obtain relations between B/A and C/A.

But I'm having particular trouble in expressing F and G in terms of C..

Algebraic derivation

Please see the attached sheet with 4 equations.
From these 4 equations, I am to get expressions for B/A and C/A. The hint I get is to express F and G in terms of C from the

last 2 equations, and use this to obtain relations between B/A and C/A.

But I'm having particular trouble in expressing F and G in terms of C..

===================================================================

I will use the notation "^" for the exponent ("power") function.

A + B = F + G ----(1)

ik(A-B) = k(F-G) ----(2)

Ce^(ika) = Fe^(ka) + ...

Solution Summary

Expressing variables in terms of other variables is investigated.
