Answer:
x = -1
Explanation:
First, add x to both sides.
-2x-6-x+x=-x-4x-8+x
-----------------------------------
Next, Refine it.
-2x - 6 = -4x - 8
--------------------------------------
Now, add 6 to both sides.
-2x - 6 + 6 = -4x - 8 + 6
--------------------------------------
Now we Simplify.
-2x = -4x - 2
---------------------------------------
Add 4x to both sides.
-2x + 4x = -4x - 2 + 4x
----------------------------------------
Simplify again.
2x = -2
-----------------------------------------
Divide both sides by 2.
2x/2 = -2/2
------------------------------------------
And we're almost finish! Just need to simplify.
x = -1.
