Simultaneous Settlement (Posted on 20120127) 

Without solving for x and y, determine all possible values of x*y in this simultaneous equation:
x+x*y = 8 and, y+x*y = 9
Note: Solving for 1/x, 1/y, x or y is similarly NOT allowed.

x+x*y = 8 and, y+x*y = 9 x + x*y + 1 = y + x*y y = x + 1 x*y = x(x+1) (parabola)
