Answer 2

The difference between 19 and 8 is 11.

Explanation:

Given:

The difference between a number and 8 is 11

Find the number.

Solution:

Let the unknown number be
`=x`

The difference between the unknown number can be written as:

`x-8`

We are given that the difference =11

So we can write the equation to find
`x` as :

`x-8=11`

Using additive property to solve for
`x`

Adding 8 to both sides to isolate
`x` on one side.

`x-8+8=11+8`

∴
`x=19`

∴ The unknown number = 19
