Question 582579
{{{-7+3n+9n=29}}} Start with the given equation.



{{{12n-7=29}}} Combine like terms on the left side.



{{{12n=29+7}}} Add {{{7}}} to both sides.



{{{12n=36}}} Combine like terms on the right side.



{{{n=(36)/(12)}}} Divide both sides by {{{12}}} to isolate {{{n}}}.



{{{n=3}}} Reduce.
