Determine whether the equation is exact. If it is$,$ then solve iR$.$

$(-sinxcosy+6x)dx-(cosxsiny-2y)dy=0$

Select the correct choice below and, If necessary, Ste in the answer box lecomplete your choice.

A$.$ The equation is exact and an implicit solution in the form $F(x,y)=C$ is $*$C$,$ where C is an arbitrary constant. $($Type an expression using $x$ and $y$ as the variables.$)$

B$.$ The equation is not exact.
