Question:
What is the ordered pair of real numbers $(x, y)$ which satisfies the equation $|x+ y-7|+ |4x - y+ 12|= 0$?

Answer:
Since the absolute value of a number is always nonnegative, we must have that $x + y - 7 = 0$ and $4x - y + 12 = 0$.  Adding these equations together, we find $x = -1$.  Thus $y = 8$, and the desired answer is $\boxed{(-1,8)}$.
