Hi,

Solving the following equation for k.

If I am understanding Your Question properly:

  n = (8k-15m)/3  |Always good to use parenthesis for clarity

 3n = 8k - 15m

 3n + 15m = 8k

 3(n+5m)/8 = k

n=8k-15m%2F3........if you have this, than both sides multiply by 3

3n=3%2A8k-3%2A15m%2F3

3n=24k-cross%283%29%2A15m%2Fcross%283%29
3n=24k-15m..add 15m to both sides
3n%2B15m=24k-15m%2B15m
3n%2B15m=24k-cross%2815m%29%2Bcross%2815m%29
3n%2B15m=24k
%283n%2B15m%29%2F24=k
k=3n%2F24%2B15m%2F24
k=%281%2F8%29n%2B%285%2F8%29m

but, if you have this:n=%288k-15m%29%2F3.......both sides multiply by 3

3n=3%288k-15m%29%2F3

3n=cross%283%29%288k-15m%29%2Fcross%283%29

3n=8k-15m......add 15m to both sides
3n%2B15m=8k-15m%2B15m
3n%2B15m=8k-cross%2815m%29%2Bcross%2815m%29

3n%2B15m=8k

3n%2F8%2B15m%2F8=k

k=%283%2F8%29n%2B%2815%2F8%29m
