The difference between a number and 23 is 8. Let the number be X.

23 - X = 8

=> X = 15

X - 23 = 8

=> X = 31

The number can be 15 or 31

The difference between a number and 23 is 8. If the number is represented by x, there are two possible cases:

x is greater that 23:

In this case x - 23 = 8

x = 31

x is less than 23:

In this case 23 - x = 8

x = 23 - 8 = 15

For the numbers 31 and 15, the difference between the number and 23 is 8.

The difference between 23 and a number is 8. What is the number?

Let us suppose that the unknown variable is x, to solve for x we can write the equation in the following way:

23 - x = 8

Isolate x, to find it's value,

23 - x = 8

23 - x - 23 = 8 - 23               Subtract 23 from both sides

-x = -15

x = 15 Answer.
