Find all pairs of real numbers such that $x + y = 10$ and $x^2 + y^2 = 56$. For example, to enter the solutions and , you would enter "(2,4),(-3,9)" (without the quotation marks).
Solving the equations, we get the solutions are (5 + sqrt(7), 5 - sqrt(7)), (5 - sqrt(7), 5 + sqrt(7)).
that seems to be incorrect
