It appears to me that the second message is also trying to teach some algebra. Statements surrounded by V are algebraic equation to be solved. Statements surrounded by W are the solutions. Shockingly, X is the variable or unknown. So we have VQBQHXHQBQV is 1 + 1=X, and next statement concludes X=2. The solution to X+1=3 is X=2. I assume the statement XPYPZP... is telling us that X,Y,Z,a,b, and c are all acceptable variable names. ps. please don't confuse astrology with astronomy!
