Springs Equivalencies

1. The problem statement, all variables and given/known data

Obtain the equivalent spring constant, Keq, for the system shown.

2. Relevant equations

For a spring system in series the Keq for that system is Keq=(k2k3)/(k2+k3)

For a spring system in parallel the Keq for that system is Keq=k1+k2


3. The attempt at a solution

So based on my free body diagrams I just added the two together to get the Keq for the combined system.

Keq=k1+k2+(k2k3)/(k2+k3)

Please help,did I do this correctly?
