If we set the expression 2(x-10) + (y-3)
equal to zero, we have an equation for
a line, which simplifies to y = 23 - 2x.
There are infinitely many ordered pairs
(x,y) that satisfy this equation, with or
without the constraint that x and y must
be positive. (And frankly, given that
Kate didn't say what x and y represent,
we don't really know if they must be
positive or not.)

Owwwww!! That makes my head hurt!!
And I even understand it.

Think that's bad? Try solving some simultaneous partial differential
equations. They're good for a migraine or two.
