Question 340439


{{{n/3+n/4=1/2}}} Start with the given equation.



{{{12(n/cross(3)+n/cross(4))=12(1/cross(2))}}} Multiply both sides by the LCD {{{12}}} to clear any fractions.



{{{4n+3n=6}}} Distribute and multiply.



{{{7n=6}}} Combine like terms on the left side.



{{{n=(6)/(7)}}} Divide both sides by {{{7}}} to isolate {{{n}}}.

Answer:


So the answer is {{{n=6/7}}} which approximates to {{{n=0.857}}}.
