Question

5.5 + 2.1x + 3.8x – 4.1

Answer 1

1.4 + 5.9x

Explanation:

You add like terms. Since 2.1x and 3.8x are like-terms, due to the variable x, you combine them. 5.5 and -4.1 are also like-terms because they both have no variable.

Answer 2

5.9x + 1.4

Explanation:

5.5 + 2.1x + 3.8x - 4.1

= 5.9x + 1.4
