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.
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.
