I can not understand what is written here. You can arrange the brackets, etc.

3. okay 6x+10y(dy/dx)-6+20(dy/dx) this is implicit differentiation

Yes!

5. Just in case a picture helps...

Top row is what you wrote, bottom row the derivative. Triangular network is the product rule.

Don't integrate - balloontegrate!
