Cope, get by (6)
I believe the answer is:
manage
I believe this is a double definition.
'cope' is the first definition.
(both can mean to get by)
'get by' is the second definition.
(synonyms)
(Other definitions for manage that I've seen before include "Supervise staff" , "Run, be in charge of" , "Handle and control the business" , "Run (eg, company)" , "Handle, cope with" .)
