Hi,

one number is 5 more than another

Question states*** the difference of their squares is 30

 y^2 - x^2 = 30       | y = (x+5)

(x+5)^2 - x^2 = 30    

   x^2 +10x + 25 - x^2 = 30

         10x = 5

           x = .5, the smaller number.  5.5 the large number y.



and...

 x=y+5;

x^2-y^2=30

x=5.5=11/2

y=.5=1/2
