In the diagram, numbers are to be placed in the circles so that each circle that is connected to two circles above it will contain the sum of the numbers contained in the two circles above it. What is the value of $x$ ?
(A) 481
(B) 381
(C) 281
(D) 581
(E) 681

We let the values in the two unlabelled circles be $y$ and $z$, as shown.

From the given rules, $y+600=1119$ and so $y=519$.

Also, $z+1119=2019$ and so $z=900$.

Finally, $x+y=z$ and so $x=z-y=900-519=381$.
