The answer would be
X= -2
First you would collect the like terms
This will convert your equation to look like this:
56-8x=72
Then you move the constant causing it to change signs
-8x= 72-56
Then subtract: 72-56
-8x=16
Then you divide -8 for both sides
X=-2
Then you are left with your answer:
X= -2
Hope this helps! :3
