    Here's what you need to do with the first one.
    You know:
    1) y = x + 2
    2) x * y = 10

    Substitute:

    x(x+2) = 10

    Solve the polynomial x^2 + 2x -10 = 0

      Second one:

      Square both sides. Get rid of the fraction by multiplying both sides by 4. Move crap around until you get it into polynomial form.


      Remember that both of these problems can be tackled with the quadratic equation.
