Answer:
   (x, y) = (3, 12)
Step-by-step explanation:
Using the given variable definitions, we can write the equations ...
   y = x + 9
   2(x +y) = 30
__
Solving the second equation for y, we have ...
   y = 15 -x
Substituting this into the first equation gives ...
   15 -x = x +9
   6 = 2x . . . . . . . . . add x-9
   3 = x . . . . . . . . . . divide by 2
   y = 3+9 = 12 . . . . substitute into the first equation
The numbers are (x, y) = (3, 12).
