Math Problem Statement
Let Q(x, y) be the statement "x + y = x - y". If the universe of discourse for both variables consists of all integers, what are the truth values?
Solution
To determine the truth values for each of these statements, let's analyze them one by one based on the given statement , defined as " ".
Step 1: Simplify the Condition
The equation implies: [ x + y = x - y \
