Instructions:

In the problem below, 'X' represents a letter, and each letter represents a member of the same group of things.

For Example: If I was using the letters T, B, S they might refer to Trout, Bass, and Salmon, which are all fish. But remember, we are dealing with things that can be 'Added' and 'Subtracted'.

The following are true statements:

(P) - (R) + (Y) = 'X'

('X') - (Y) = B

However,

No letter added to it will give you two of that letter.

That is, 'X' + 'X' = 2X would NEVER be true.

Question:

What is the only letter 'X' can represent?

### Hint

"Adding" and "Subtracting" these things as equations is feasible. Even adding them in 3D. However, "Subtracting" them in 3-D is like finding a pot of gold....### Answer

Solution: 'X' can only represent the letter G, [GREEN]Basis:

The letters represent COLORS, which can be 'ADDED' and 'SUBTRACTED' from (or to) each other, producing a new result.

Example:

Purple (P) is a color that consists of both Red (R) and Blue (B).

Thus, R+B=P.

Also, 'SUBTRACTION' works:

Purple (P), consisting of two colors added together (Red [R] and Blue [B]), can have one of those colors subtracted to leave the remaining color (in an equation this works, but don't try it with real paint):

(P) - (R) = (B) [Purple minus Red Equals Blue]

Therefore, I can get 'G' (Green) by doing this:

(P) - (R) + (Y) = G

Hint Explained:

"Adding" and "Subtracting" these things as equations is feasible. (as demonstrated). Even adding them in 3D. (Mixing paint, for example). However, "Subtracting" them in 3-D is like finding a pot of gold....

on the other side of the RAINBOW. (BIG HINT).
