Answer:

The two numbers are 6 and 19.

Step-by-step explanation:

To find these, we must first set the first number as x. Then we can set the second one in terms of x as 2x + 7.

Now that we have these values, we can add them together and set equal to 25.

x + 2x + 7 = 25

3x + 7 = 25

3x = 18

x = 6

With the first value being 6, we can solve for the second by using the equation built.

2x + 7

2(6) + 7

12 + 7

19
