You can do it like this:

$e^2x=sin(x+3y)$

Take the derivative with respect to $x$ of both sides implicitly:

$D[e^2x]=D[sin(x+3y)]$

$:.2e^2x=cos(x+3y).d((x+3y))/dx$

$:.2e^2x=cos(x+3y)(1+3(dy)/(dx))$

$:.(2e^2x)/(cos(x+3y))=1+3(dy)/(dx)$

$:.3(dy)/(dx)=(2e^2x)/(cos(x+3y))-1$

$:.dy/dx=(2e^2x)/(3cos(x+3y))-1/3$
