You can put this solution on YOUR website!
2x=8
-------
Maybe the problem is not knowing what you want to do.
What is the answer to 2x=8?
It depends on the question.
------------
If you say, solve 2x=8 for x, then
2x=8
divide by 2
x = 4
-----------
But "what is the answer to..." does not specify your goal.
Try it again.
