You can only add or subtract common things. 2x and -8x are common, and -7 and +8 are the same.
So, you rearrange it to be this:
2x -8x -7 +8
Then you solve it, solving each pair at a time.
2x -8x equals -6x. You have to make sure to keep the x.
-7 +8 equals 1.
Therefore, the answer is: -6x+1
You can't solve it anymore because the two numbers are not common.
Hope this helped :)
