Question 685489
{{{39+9+9n=111}}} Start with the given equation.



{{{9n+48=111}}} Combine like terms on the left side.



{{{9n=111-48}}} Subtract {{{48}}} from both sides.



{{{9n=63}}} Combine like terms on the right side.



{{{n=(63)/(9)}}} Divide both sides by {{{9}}} to isolate {{{n}}}.



{{{n=7}}} Reduce.
