2
(x, y) = (-3, -3) or (3, 3)
89
The solutions are: x = 4, y = 2 and x = -4, y = -2
They touch each other at (0, 100) on the x and y axis.

(2, -2)
The solutions are: x = 4, y = 2 and x = -4, y = -2
y equals x plus 4 when y equals 0 then x equals 2i i is the square root of negative 1
The two rational solutions are (0,0,0) and (1,1,1). There are no other real solutions.
Y = 4/x^2
They touch each other at (0, 100) on the x and y axis.
If x = sin θ and y = cos θ then: sin² θ + cos² θ = 1 → x² + y² = 1 → x² = 1 - y²
They are +/- 5*sqrt(2)
Two equations: a linear one in y and a quadratic in x.
