Hi

I am trying to solve the following puzzle.

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.

Thank you
