List all the numbers that are a distance from 6 away from the number 7

Answer 1

Let x be a number such that

$|x-7|=6.$

Solving the above equation for x we get:

$\begin{gathered} x-7=\pm6, \\ x=7\pm6, \\ x=1\text{ or x=13.} \end{gathered}$

Answer: The numbers that are a distance of 6 away from the number 7 are:
