Simplify - 10x - 2x + 3x.

-9x

9x

11x

Here is your answer: Combine like terms: - 10x+-2x=-12x+3=-9x Your answer is - 9x or A also its not B because when adding - 10x-2x you have to use KCC because your subtracting a negative also its not C because its not positive because of my calculator it was a negative from the first solution.

-10x - 2x + 3x

combine like terms

= (-10 - 2 + 3) x

= - 9x

answer

-9x
