Question 1110891
n, d, q
nickels, dimes, quarters


This is the resulting system literally according to the description:
{{{system(5n+10d+25q=320,q=d+4,n/q=5)}}}


-

Simplify the cents-count equation, and write the next two equations in terms of the variable, q.
{{{system(n+2d+5q=64,d=q-4,n=5q)}}}



{{{5q+2(q-4)+5q=64}}},  single equation in one variable, q;


SOLVE FOR q, and then use this value to evaluate n and d.
