1.22. We have two identical glasses. Glass 1 contains x ounces of wine; glass 2 contains x ounces of water (x ≥ 1). We remove 1 ounce of wine from glass 1 and add it to glass 2. The wine and water in glass 2 mix uniformly. We now remove 1 ounce of liquid from glass 2 and add it to glass 1. Prove that the amount of water in glass 1 is now the same as the amount of wine in glass 2.
