Please help me with resistors in parallel/series - with many variables :)

Three identical resistors are connected in parallel. The equivalent resistance increases by 700 W when one resistor is removed and connected in series with the remaining two, which are still in parallel. Find the resistance of each resistor.

Im totally confused how to do this..
I know in parallel, voltage remains the same, wheras in series, current stays the same

please kick in the right direction on how to solve this (with many unknowns :) )
Thanks!

Do you really mean 700 W as in power?
Because then you would have to many unknowns, like the current for instead.
If you mean $$700 \ohm$$, as in resistance, then it is not to hard to calculate the answer.
