@Mani: Algebra problem. Treat x as an independent variable and write it as a quadratic in y: y^2 - xy - y + x^2 - x - 2 = 0 Factor: y^2 - (x + 1)*y +(x^2 - x - 2) = 0 Use the quadratic formula to solve for y: y = ... (you do it) Look at the result to see what are valid values for x and what the resulting y values are. Valid values for x will ensure that the argument of the square root is non-negative and that you don't divide by zero.
