Correct! So you do know! Now solve for dy/dx.

Yes you differentiated correctly but now you should express dy/dx in term s of x and y. In other words, isolate dy/dx.

i got 2  cosxy *y / x = dy/dx

No, if\[(y +x \frac{ dy }{ dx })\cos (xy)=2\]then\[y \cos (xy)+x \cos (xy)\frac{ dy }{ dx }=2\] \[x \cos (xy)\frac{ dy }{ dx }=2y \cos (xy)\] \[\frac{ dy }{ dx }=\frac{ 2\cos (xy) }{ x \cos (xy) }\]
