Which expression is equivalent to 8x − 2x + 4 and why?

4 + 6x, because (8x − 2x) + 4 = 6x + 4 = 4 + 6x
10x, because 8x − 2x + 4 = 6x + 4 = 10x
8x + 2x, because 8x − (2x − 4) = 8x + 2x
14x, because 8x − 2x + 4 = 8x + 6x = 14x

Answer:

4+6x | because (8x − 2x) + 4 = 6x + 4 = 4 + 6x

Step-by-step explanation:

Hi. I am adding my response again because my answer was right and it should not have been taken down. The other answer should have been taken down.

You can only subtract coefficents so, 8x - 2x = 6x

So, the correct answer is 6x+4 and because it is addition it can be rearranged to say 4 + 6x
