-2x because you are taking away 4-6x and the variable is x
Answer:
see below
Step-by-step explanation:
The two marked points are equidistant from their average, which is ...
(-3 +9)/2 = 6/2 = 3
The distance they are from that average is 9-3 = 3 -(-3) = 6.
So, you want an expression that is equivalent to ...
|x -3| = 6
Subtracting 1 from both sides of this equation gives you the one seen in choice B:
|x -3| -1 = 5
3 + j
____ = 2
