The difference between a number and 8 is 11

quester [9]

Answer:

The difference between 19 and 8 is 11.

Step-by-step 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
