Answer:

B. 2x

Skills needed: Systems Evaluation, Addition of Equations

Explanation:

1) We have a system of two equations and we are adding them together. We need to solve for the x-value of when they are both added together.

We are adding
3x with
-x

2)
-x just means
-1x

---> This means it is:
3x+-1x

-------> When you are adding a negative, you are subtracting a positive:


3x+-1x=3x-1x=2x


2x is your answer.
