Yes you must solve for x
Answer: BLUE
Step-by-step explanation:
When factoring, it's easier to "pick out" the GCF first because it makes it simpler to factor even further. Otherwise, you will be troubled with lots of numbers and variables, so it will just get confusing.
6 - 4x = -2x +2
6 = 2x +2
4 = 2x
2 = x
