For other ppl looking at this question here's the answer.
First you have to put
x+8 and
2x-1 equal
Like this
x +8=2x-1
Then you have to get x on one side
So Add 1 to both sides which cancels out the
-1
And you have
x+9=2x left
Then subtract x from both sides
And you get
x=9.
hope this helps you; if you need help pm me :).

you have to first get the x by its self by canceling it out so subtract 3 and what you do to one side you do to the other. so that means that -3(-3) two negatives = a positive so thats 6 so what you should have now is x+6
