The answer to the question
Answer:
C. x - 10 + 9x - 3
Explanation:
We need to simplify each option, so we need to identify the like terms and then add them.
<em>Option A.</em>
- 7x + 3x - 16 + 3
(- 7x + 3x) + ( - 16 + 3)
- 4x + (-13)
- 4x - 13
<em>Option B.</em>
-21x + 4 + 11x + 9
(-21x + 11x) + (4 + 9)
-10x + 13
<em>Option C. </em>
x - 10 + 9x - 3
( x + 9x) + (-10 - 3)
10x + (-13)
10x - 13
<em>Option D. </em>
-2x + 8x - 20 + 7
(-2x + 8x) + (-20 + 7)
6x + (-13)
6x - 13
Therefore, the answer is C. x - 10 + 9x - 3
