Answer:

The "one number" is equal to 4 and "another number" is equal to 6.

Explanation:

1. We can write an equation for "one number": X = 2n - 8 (X is one number and another number is N)

2. Since their sums are 10 we can write it was X + N

3. Plug in the value of X to get: 2n - 8 + N = 10

4. Put 8 to the other side to get + 8 --> 2n + N = 10 + 8

5. Now you form the equation 3n = 18

6. N = 18 / 3 which is 6

7. To get X you do 10 - 6 which is equal to 4

8. To make sure the answer is correct plug in the values into the equation: 4 = 2(6) - 8 which simplifies to 4 = 12 - 8

Therefore, one number is equal to 4 and another number is equal to 6
