If I'm reading the question right, you're asking for [tex]13+2n[/tex], right? Well, if we assume this equation equals zero, then we can subtract 13 from each side to get [tex]2n=-13[/tex]. Divide 2 from each side and for your final answer, drumroll please, ........ [tex]n=-13/2[/tex]. Hope that helps.
