SOLUTION: Find all pairs of real numbers (x,y) such that x + y = 6 and x^2 + y^2 = 28. If you find more than one pair, then list your pairs in order by increasing x value, separated by comma

Question 1086136: Find all pairs of real numbers (x,y) such that x + y = 6 and x^2 + y^2 = 28. If you find more than one pair, then list your pairs in order by increasing x value, separated by commas. For example, to enter the solutions (2,4) and (-3,9), you would enter "(-3,9),(2,4)" (without the quotation marks).
*((3-sqrt5),(3-sqrt5))((3+sqrt5),(3+sqrt5)) is not the answer

No, it's not the solution.
But (3-sqrt%285%29,3%2Bsqrt%285%29) and (3%2Bsqrt%285%29,3-sqrt%285%29) is the solution.
