Answer 1

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.

Answer 2

2x is the correct choice!!
