Hello, Im new at here, and this will be my first question...

I have $$2x+4y=0$$ but don't know how to solve it. Can someone help me? Thanks!...

Well, it looks like homework. In this case, the following sage code will not work to feel at home:

sage: var( 'x,y' );
sage: solve( 2*x + 4*y == 0, x )    # solve in x
[x == -2*y]
sage: solve( 2*x + 4*y == 0, y )    # solve in y
[y == -1/2*x]
