Answer:

The numbers are 9 and 16.

Step-by-step explanation:

It is possible to solve this problem without using algebra and all the  equations. well one number is 7 more than the other, but they add to 25. If you subtract the difference of 7 first, you will be left with the sum of two equal numbers.

25-7=18

18/2=9   The one number is 9 and the other is 7 more than 9, so you would do  (9+7 = 16)
