Answer:
D. 3
Step-by-step explanation:
Assuming the model represents an equation, the following can be deduced:
On the left side of the equation, the model shows we have 3 "x's", and 6 "1's". Let this represent:
3x + 6
On the right side of the equation, we have 2 "x's" and 9 "1's". Let this represent:
2x + 9.
The model would represent the equation below:

Solve for x
(Subtracting 2x from both sides of the equation)

(subtracting 6 from both sides of the equation)

Answer:
-6-(-2) is equivalent to
-6 +2
and 2-6
