Question 448617
{{{n+n/3=600}}} Start with the given equation.



{{{3(n)+cross(3)(n/cross(3))=3(600)}}} Multiply EVERY term by the LCD {{{3}}} to clear out the fraction.



{{{3n+n=1800}}} Multiply and simplify. This is where you made your mistake. You forgot to multiply the first 'n' by 3.



{{{4n=1800}}} Combine like terms on the left side.



{{{n=(1800)/(4)}}} Divide both sides by {{{4}}} to isolate {{{n}}}.



{{{n=450}}} Reduce.

Answer:


So the answer is {{{n=450}}}
