By using contradiction, prove that : If y + y = y then y = 0. Solution : Let P : y +y = y & Q : y = 0 To prove : (P ∧ ¬Q) is false as (P ∧ ¬Q) is false ,then¬ (P ∧ ¬Q) is true, and the equivalent statement P ⇒ Q is likewise true. P : y + y= y and ¬Q : y~= 0. (P ∧ ¬Q) means : Then 2y =y and as y ~= 0 we can divide both sides by y.
