Question 1166493
n, d, q


{{{system(d<n,and,q/d=3)}}}


That also shows {{{q=3d}}}.


{{{5n+10d+25q=745}}}
{{{n+2d+5q=149}}}
substituting for q,
{{{n+2d+15d=149}}}
{{{n+17d=149}}}



Not yet finished, you want whole numbers n and d so that
{{{system(n>d,and,n+17d=149)}}}.

.

.
(just a quick thought - what if d were 8?  Whole n greater than 8 ?)
