So, we have <span>xy=35
Since that, the first thing you should do is to </span><span>differentiate with respect to x
(look at the pic. 1), as you can see this is simply 1, which means you have to simplify
Then we need to perform solving for </span> for dy/dx as we are about to get <span>the derivative of y with respect to x. pic.2
Get back to the oroginal function, now we can substitute this for y to get the func which will depend only on x pic.3
Then pic.4
