Answer:

x = 4 and x = 6  

Step-by-step explanation:

There are two solutions to an absolute value equation.

If |x - 5| = 1, then  

x - 5 = -1 and  

x - 5 = +1.

1. Solve x - 5 = -1

Add 5 to each side.

x = 4

2. Solve x - 5 = 1

Add 5 to each side.

x = 6

The solutions are x = 4 and x = 6.

3. Number line

The number line would have markers at 4 and 6.

It should look like the image below.
