Question 786733
{{{n+4(1+3n)=15}}} Start with the given equation.



{{{n+4+12n=15}}} Distribute.



{{{13n+4=15}}} Combine like terms on the left side.



{{{13n=15-4}}} Subtract {{{4}}} from both sides.



{{{13n=11}}} Combine like terms on the right side.



{{{n=(11)/(13)}}} Divide both sides by {{{13}}} to isolate {{{n}}}.

Answer:


So the solution is {{{n=11/13}}}
