Transcription: A screenshot of a tweet by a user called 'llama in a dracula cape (@LlamaInaTux)'. The text of the tweet is as follows.
Flight attendant: Do we have a doctor on board?
Me: I have a PhD in Mathematics
Flight attendant: one passenger is having a heart attack and one passenger is having an asthma attack
Me: nodding That makes two
Did he just claim that
1x + 1y = 2
without having a second equation to resolve for x and y?
