I am struggling with this puzzle along with my kid, who's in algebra class. The conditions are: 1. (X.6)(y.4) = 288 2. X^2-y^2 = -5 3. X.7-3.x = 19 4. (Y-x)/(x-y)= -1 x and y has to be the same numbers throughout the 4 given conditions. Can someone please help?

I'd say x=4 and y=3 but then #2 would have to equal 7 and #3 would have to be x7-3Y=19. I don't know.

Are the variables case sensitive? IOW, is X same as x? is Y same as y? If the variables are not case sensitive, the given 4 conditions are inconsistent. There is no solution.

BTW, the fourth condition is an identity if the variables are case insensitive.. You can ignore that. But then that makes me believe the variables are case sensitive.

You are some kind of math genius. Or something.

I was thinking more along the lines of some kind of formula where triangle equals something like "x - y" and box equals something like "a x b" and when the triangle and box are replaced exactly with those formulas, the order of operations would dictate how it is then solved. So while x - y might equal 13, and 13^2 is 169, x - y^2 would not equal 169. Think outside the triangle. Not a math genius, but I did score an 800 on the math portion of the PSAT half my life ago.
