Proof by Contradiction: Example 2 Theorem: For all real numbers x and y, if x is a rational number, and y is an irrational number, then x+y is irrational. Proof  Assume x is any rational number, y is any irrational number and that x+y is a rational number.  Then x+y = a / b for some a  Z and some b  Z +  Since x is rational, x = c /d for some c  Z and some d  Z +  Then (c /d/
