Algebra, check please?

posted by Allyson

And then I wrote down 5n+10
But what would do after that? I know that the equal sign basically cuts it inhalf so that it's two problems.. but I just don't know what to do from that point.
Help please?

    also expand the right side, so your equation is
    5n + 10 = 3 + 6n
    10-3 = 6n-5n
    7 = n
