WebBut this is the same as saying yRx and xRy, so ySx. So S is symmetric. Now assume xTy and yTx. The first relation implies xRy and yRx/ and the second implies yRx and xRy/ . It is impossible for xRy and xRy/ to hold simultaneously, and in particular it is impossible when x 6= y. So x 6= y implies either xTy/ or yTx/ (or both). guyana tourism industry
