    I'm assuming you know about solving quadratic equations

    x + y = 10

    xy = 20 y = 20/x

    x + y = 10

    x + 20/x = 10 (multiply by x)

    x^2 + 20 = 10x

    x^2 - 10x + 20 = 0

    you will now have to use the quadratic formula to solve this as the answers are not whole numbers. It's complicated to type it out so I'm going to leave it to you or someone to insert a written answer.
