apologiabiology
so thi sis really simple since you have an equal sign so



(n/3)-(5n/6)=1/3
to subtract fractions, make the bottom number the same
n/3 times 2/2=2n/6
(2n/6)-(5n/6) or (2n-5n)/6 so
-3n/6=1/3
multiply both sides by 6
-3n=6/3=2
-3n=2
divide both sides by 3
-n=2/3
mmultiply boht by -1
n=-2/3
tada
n=-2/3
[tex]\frac { n }{ 3 } -\frac { 5n }{ 6 } =\frac { 1 }{ 3 } \\ \\ n\left( \frac { 1 }{ 3 } -\frac { 5 }{ 6 } \right) =\frac { 1 }{ 3 } \\ \\ n\left( \frac { 2 }{ 6 } -\frac { 5 }{ 6 } \right) =\frac { 1 }{ 3 }[/tex]

[tex]\\ \\ -\frac { 3 }{ 6 } n=\frac { 1 }{ 3 } \\ \\ -\frac { 1 }{ 2 } n=\frac { 1 }{ 3 } \\ \\ \frac { 1 }{ 2 } n=-\frac { 1 }{ 3 } \\ \\ 2\cdot \frac { 1 }{ 2 } n=-\frac { 1 }{ 3 } \cdot 2\\ \\ n=-\frac { 2 }{ 3 } [/tex]
