Answer:
The answer is x = 7
Explanation:
The lines are the same lengths so you start by setting the top things on the line to the bottom ones. it'd look like this:
9 + x - 6 + 3 = 2x -2
Then you'd solve and that would look like this:
9 + x - 6 + 3 = 2x -2 *add like terms first*
5 + x = 2x -2 *then move x to one side by subtracting*
-x -x
5 = x - 2 *then add 2 to both sides*
+2 +2
7 = x
