If still need help - you'll need to tell us what you learnt from that site.
3x-1=4
The way I understand it is that you want to get the x by itself so I turn the-1 into a positive 1, and move it by the 4
3x -1 =4
+1 +1
_________
next I add 4+1 which is equal to 5
3x -1 =4
+1 +1
_________
5
Do I have to do anything else? In the example there was not a number before the x.

You have to write the answer, at some point!
x = what?
How about writing stuff horizontally?
3x - 1 + 1 = 4 + 1
You can simplify, at this point because you know the values for -1+1 and 4+1.
3x = 5
Now, use Denis' hint, to finish solving for x.

Linear Equation...Solve for x
3x - 1 = 4
Add 1 to both sides.
3x - 1 + 1 = 4 + 1
On the left side, we are left with 3x and on the right side we now have 5.
3x = 5
To find x, divide both sides by 3. Can you finish now?
Also, this question belongs in the basic algebra category.
