Find two resistors given series and parallel resistances

[Chantry09]

Homework Statement

Two resistors, when conected in series have a total resistance of 12.9KOhms, and when connected in parallel a combined resistance of 2.988KOhms. Derive the value of the individual resistors.

Homework Equations

R = R1+R2 ---Series
1/R = 1/R1 + 1/R2

The Attempt at a Solution

Ive tried a few different things but i don't get the right answer :S

Perhaps if you showed your working we could help you out.

HINT: You have a system of two simultaneous equations, with two unknowns.
