{{{system(n+d+q=16,5n+10d+25q=215,n=d+q-8)}}}


Simplify the money equation, and
...


{{{system(n+d+q=16,n+2d+5q=43,d+q=n+8)}}}

<s>If you look at E1 and E3 in this last form of the system, you might be able to quickly solve for n.</s>


If you look at the first equation and the third equation in this last form of the system, you might be able to quickly solve for n.
