if I had never had any exposure to programming, and you told me that a equals ten, b equals twenty, and a equals b, I would say that one of these three equations is obviously false (the system of three equations has no solution), you're full of shit, and probably made a mistake and expect me to put 0,0 for a and b respectively. Or I would guess randomly or ignore the question.
