Yes, in algebra, X and Y can equal the same number. This is frequently the case in equations where X and Y are variables that represent the same unknown quantity. For instance, consider the equation X + Y = 6. In this equation, X and Y could represent any two numbers that add up to 6. For example, X...

Yes. X and Y are unknowns, so can represent any number. They can be equal to each other.

With this algebraic truth in mind, let's take a quick look at the simplest reason why two variables can have the same value, namely X and Y. Again, remember that there is absolutely no algebraic rule that states that two or more variables can not equal the same number.

However, in specific situations, such as symmetry problems or specific mathematical contexts, X and Y might represent the same value. In general algebraic expressions, X and Y are considered independent unless the problem specifies otherwise.

It is the same as asking if you have the same money in your pocket as your friend does. The short answer is "nobody knows". You need to establish certain relations(equations) to ascertain anything about X and Y
