I can't seem to wrap my head around this today. Any tips, insight, or otherwise appreciated. Please let me know if you can see the image.

Per forum rules (https://www.chemicalforums.com/index.php?topic=65859.0) you have to show your attempts at answering the question/solving the problem to receive help. But I will give you a hint: reverse the second equation.

Hi, thanks for the hint. I reversed the second equation and multiplied by .5, and I multiplied the third equation by .5 as well. I got +155.65 kJ as the ΔH.
