If you can prove otherwise you will probably get a nobel prize..Good luck :-) The Scientist Are you not familiar with the concept of vacuous truth in mathematics? Wonkish Look , if Y was an empty set or zero, and then you add 2 it becomes 2 and no longer empty so Y which equals the empty set would equal zero not two. Y cannot be empty after adding 2 so your proposition fails The Scientist Mathematical logic does not seem to be your strongest point. Consider a simple conditional statement: If 0 = 1 then 1 =2. If you look at the truth values of this conditional then you must conclude that the statement is true. The statement is vacuously true, but nonetheless true---there is no discrimination between a true statement (T->T, or F->F) and a vacuously true statement (F->T) in mathematics. Now onto the OP's problem. If y < y + 2 and y + 2 < y then y = y + 2. Let p = y < y + 2, q = y + 2 < y, and r = y=y+2 Now we can look at the dichotomous outcomes and determine the falsity of the statement: (p and q) => r (T and F) => F F => F T Whenever the antecedent is false the conditional is automatically true. If you do not believe this, then by all means go ahead and construct a truth table and see it for yourself. Like I said, you must not understand the concept of vacuous truths in mathematics. It's a pity, I would have expected someone with the username "Scientist" to at least have a basic understanding of mathematical logic. Wonkish T works. |

It is the same as writing Y+2=X. To solve you need one of the unknowns. Going with your original equation some say infinity BUT in a real world situation it is about as real as a hooker telling you that she loves you. |

Quoting: Google is no help. Just sarcastic nerd replies. Borian No problem, piece of cake, think of it this way. If Y + 2 = Y then Y - Y + 2 = 0 which is the same as 2 = 0. So in other words, if Y + 2 = Y then 2 = 0, therefore since 2 does not equal 0 we may conclude that Y + 2 does not equal Y ever. In other words the fuckin thing doesn't have a solution. |

YolitaYoUser ID: 6275718 Bulgaria 11/05/2012 05:43 AM Report Abusive Post Report Copyright Violation | In fact Y + 2 = Y is not the same as Y = Y + 2 Y = Y + 2 has the meaning of "next Y" - variable value, which increases by two every time, when we need to define new YY + 2 = Y has the meaning of variable to which value we added two and it's still the sameThere is difference between the two equations Nothing in this universe occurs by accident. |
