Real numbers X and Y satisfy
\(\begin{align*} x + xy^2 &= 250y, \\ x - xy^2 &= -240y. \end{align*}\)
Enter all possible values of X separated by commas.
+36916 From first equation y/x = (1+y^2) /250
From second equation y/x = (1-y^2)/ (-240) Equate these two equations to solve for y = +- 7
sub in these values of y to calculate possible values of 'x'
