Knowing profit is y-x/x we can get the 2 information than:

y-x/x is equal to y/x - x/x = 5/4 - 1 = 1/4 = 25%

Is it correct to get like this?

You can simplify the profit / x equation (y-x) / x to be (y/x) - (x/x) or (y/x) - 1...from that you can skip all of the math you did for step 2 in the video and see that statement 2 is sufficient.
