Answer: -x + 2

Explanation:

So I assume that the question would be set up like this if you are finding the sum of all 3 terms:

(x + 5) + (-4x - 2) + (2x - 1)

1) Take out parentheses

x + 5 - 4x - 2 + 2x - 1

2) Add like terms

For the x terms:

x - 4x = -3x

-3x + 2x = -x

For the other terms:

5 - 2 = 3

3 - 1 = 2

The sum of the terms is -x + 2
