- [Subtraction] Combine like terms (x²): -5x + 5x
- [Addition] Combine like terms (x): 0
Answer: second option
Step-by-step explanation: To solve this problem, we will need to plug in the value of “x” into our equation to see if it makes sense.
Let’s start by going in order.
-4.9 = -5.7 + 10.6 = 4.9
This will not be the answer because it’s positive 4.9 not negative.
