i have two equations -r^2/wc
divided by r^2-(1/(wc)^2)
equals -7903

and r/(wc)^2
divided by r^2-(1/(wc)^2)
equals 3287



w is a known quantity. How do I start to solve for r and c.

1. Step:
Divide the equations by each other; this gets rid of the difficult denominator, and you may express "c" in terms of "r" (or the other way around, if you prefer that).
2.Step:
Insert the given expression for "c" into one of your ORIGINAL equations.
You have now a single equation in "r" which you may solve.
3.Step
With your "r"-solutions, put these into the relation you derived in 1. between "c" and "r" to determine the corresponding solving values for c.
