Answer:
These add up to -5x
Explanation:
What you have here is three multiples of x being added and subtracted. Since they are all in the same format (a constant number times x), you can simply add the numbers together.
A potentially easier way to look at it is to think of x as just some type of item. Maybe x is an apple. This means that you are taking -14 apples, subtracting 10 apples, and adding 19 apples.
With that in mind, all you need to do here is take the sum of the numbers, and multiply that by x to get the answer.
