## Problem

Give the only positive value of in .

## Solution

To figure out all possible values of , we have to solve the inequality.

First, we have to make sure that only one side has the variable x. To do that, we subtract x from both sides so only the left side has x in it. We have

Subtracting 5 from both sides gets , so . Therefore the only positive value of is .
