At least it's not an imaginary disease where the medicine could have complex side effects.
Not sure that I'd trust a doctor that has WebMD visible on their computer :)
At least he can calculate a minimal diagnosis set ;)
I get the joke!
The system if equations is inconsistent, meaning it has no solution, so no one can get a solution and the doctor can't help.
This is because if you multiply the first equation by negative two...
Yet the third equation sets the new left hand side equal to 5
Since -6 doesn't equal 5, it is impossible to get any solution out of the system!
And yes I am a nerd
Oops... I meant "of", not "if"
WebMD on the doctor's screen? LOL!
Thanks @Pirnez for your explanation. I had to pretend I got the joke until I read your post! :)
