I'm stuck on part B of this question:

A system does 125 J of work on environment and gains 79 J of heat in the process. Find change in internal energy (delta U, abbreviated dU)of
a. the system and b. the environment.

A. Find dU of the system
W = 125 J
Q = 79 J
dU = Q - W
dU = (79 J - 125 J) = -46.0 J

B. find dU of the environment
