document.write( "Question 1085964: 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). \n" ); document.write( "
