Hi! The correct answer is 4x+4!
Step-by-step explanation:
~Combine like terms~
Answer:
4 ( x + 1 )
Step-by-step explanation:
Easy. Just combine like-terms!
Rearrange it as x + 3x + 12 - 8
Combine x + 3x --> 4x
Combine 12 - 8 --> 4
You can't combine 4x and 4 because they're not like-terms. Meaning you'd get 4x + 4. You then simplify if needed as 4(x+1)
