This type of problem is analyzed using the superposition
theorem..
One source is +10 VDC
The second source is a 10 V pk-pk sine wave.

Just add the two results for the answer, into a common load.
For the DC, allow time for the transient to settle....

If you can use PSPICE, or the equivalent, you can do this
easily , with additional experiments which may improve your
understanding......

of the posters here who have a lot of time on their hands and
have no tolerance for those who are just learning their craft....
