# If the difference between two numbers is 15 and their sum is 47, what are the two numbers?

**Question: If the difference between two numbers is 15 and their sum is 47, what are the two numbers?**

Let's call the two numbers "x" and "y".

From the problem, we know two things:

The difference between the two numbers is 15:

x - y = 15

The sum of the two numbers is 47:

x + y = 47

We can solve this system of equations simultaneously to find the values of x and y.

One way to do this is to add the two equations:

(x - y) + (x + y) = 15 + 47

Simplifying this expression, we get:

2x = 62

Dividing both sides by 2, we get:

x = 31

Now we can substitute x = 31 into one of the equations to find y. Let's use the equation x + y = 47:

31 + y = 47

Subtracting 31 from both sides, we get:

y = 16

Therefore, the two numbers are 31 and 16.
