I also mentally started thinking about integral solutions. I wonder if it's also because of the variable names... a,b,c tend to be used to represent integers (e.g. Fermat's Last Theorem, Euclid's algorithm etc).
x and y are more commmonly used to represent real numbers.
Random aside: once in high school I took a math puzzle test. The only problem I skipped was because they asked for "integral solutions." I knew the word "integral" only as belonging to calculus, about which I knew nearly nothing at the time. If I had realized in context it just meant "integer" I could have done it!
Thanks for pointing that out. I'll use X and Y next time I share this story. Of course my daughter wouldn't have known at the time about the distinction, and neither did I - it having been too long since doing algebra ;)
I happen to agree we should have an election, but I would point out:
1) Unlike EU commissioners, people can vote Theresa May out at the next general election.
2) The UK has a parliamentary democracy. It is not a presidential system. Theresa May was elected by her constituents.
3) Of the 14 prime ministers since the end of the Second World War, half of them (including Theresa May) assumed office between elections.
