a system udergoes a process consisting of the following 2 steps-

1. absorbs 79J of heat while 26J of work is done to it
2. system absorbs 26J of heat while preforming 79J of work

what is overall ÄE?

is it 52J?

I think you are correct but get a second opinion.
Step 1: Change in E2 = q+w ; 79+26=105J

Step 2: Change in E2 = 26-79=-53J

Change in E overall = Change in E1 + Change in E2 ; 105-53=52J

So yes, you are correct.
