Question 979257
Taking that description and converting directly into symbolism,
let n be "a number".



One way:
{{{2n*3=(1/2)n}}}
{{{6n=n/2}}}
{{{12n=n}}}
{{{n=0}}}
This is the only possibility.


The other way:
2n, 3n,....? result is n/2
This is not precise enough to symbolize in any precise comprehensible way.
