Answer:

43 and 5

Step-by-step explanation:

Let's let the two unknown numbers be a and b.

Their sum is 48, therefore:

a+b=48

And their difference is 38. In other words:

a-b=38

We now have a system of equations. To solve, we can use substitution. First, add b to both sides in the second equation:

a=38+b

Substitute this into the first equation:

(38+b)+b=48

Combine like terms:

2b+38=48

Subtract 38 from both sides:

2b=10

Divide both sides by 2:

b=5

So, one of the numbers is 5.

The sum of them is 48. Therefore, the other number is 48-5 or 43.

So, our two numbers are 43 and 5.

And we're done!
