{{{system(n/p=2,d-n=2,q=d+n)}}}


{{{system(n=2p,d-n=2,q=d+n)}}}


{{{system(d-2p=2,q=d+2p)}}}


{{{system(2p=d-2,2p=q-d)}}}

{{{d-2=q-d}}}

{{{q=2d-2}}}

q ,d, p, n, must be a whole number or better, some natural number.  1 will not work for d; 2 MIGHT work for d.    If not work, go upward from there (and keep going, to find more possible results),...


{{{system(d=4,n=2,q=6,p=1)}}}


4 dimes
2 nickels
6 quarters
1 penny
