Are these two trains really equal? What could we write?

    Africa:
    B+w=o
    2d=o+r
    B+w+2d=2o+r

      Wow, you've thought about this carefully, Africa. The first two lines lead on to the third, and help to fix this picture. I can see now that if you added a white to the left train, and a red to the right train, they would be the same length.

    Answer from Tjan: 2dg+1b=2or

      Tjan, you've written what's there... but there is a problem with what's there. Can you see it?
