Answer is in the screenshot.
You can turn 5 into 10/2 and add to x/2
then you need to use simple algebra to left the x alone in the equation so you need to multiply both sides by 2 so you get
2y=10+x
then you need to subtract both sides a 10 so
2y-10=x
now change the x to f'(x) and y to x so:
f'(x)=2x-10
Please take a photo of this problem... it looks very hard when it is written in the way you did.

If I am reading this correctly the answer should be 1,977,326,743x^3</h3>
Nobody can really answer this unless you can just give a random equation like 5*x=25 something like that
