68. Interesting observation that a right and a left shoe might have two different values

But if this were the case, you cannot solve the bottom equation, as a right shoe could be anything from zero to 10, zero and 10 being a possible combination. Following from this, the cone in the bottom equation is at a very different angle than any of the cones in the third equation.

To make the a single shoe, regardless of left or right, equal to 5, one pair of shoes in the first equation would have to be either two left shoes or two right shoes. In third equation, the cones would have to be distinct, not overlapping, and at the same angle, and the cone in the last equation would need to be at that same angle. This would remove any ambiguity and force the solution of the last equation.
