Question

calc

Answer 1

ok start differentiating both sides first

Answer 2

\[x+2y=xy\]
diffrentiate it

Answer 3

\[\frac{ d }{ dx}(x+2y)=\frac{ d }{ dx}(xy) \\ \frac{ d }{ dx }(x)+\frac{ d }{ dx }(2y)=\frac{ d }{ dx }(xy)\]

Answer 4

so ok?

Answer 5

no now diffrentiate it

Answer 6

\[1+2\frac{ dy }{ dx }=x \frac{ dy }{ dx }+y\\ \frac{ dy }{ dx }[2-x]=y-1\\ \frac{ dy }{ dx }=\frac{ y-1 }{ 2-x}\]

Answer 7

yW!! :)
