In my spare change drawer, I have a lot of coins. I have some quarters and some nickels. I actually have twice as many nickels as quarters. I also have some pennies and dimes. There are two less pennies than nickels and five more dimes than quarters. I know that I have $5.65. How many of each coin do I have?

\n" ); document.write( "Equations:
\n" ); document.write( "n = 2q
\n" ); document.write( "p = n-2
\n" ); document.write( "d = q+5
\n" ); document.write( "p + n + d + q = 565 cents
\n" ); document.write( "--------------------------------
\n" ); document.write( "Substitute and solve for \"n\":
\n" ); document.write( "(n-2) + n + (q+5) + q = 565
\n" ); document.write( "----
\n" ); document.write( "(2n) + 2q = 562
\n" ); document.write( "2n + n = 562
\n" ); document.write( "3n = 562
\n" ); document.write( "n = 187 1/3
\n" ); document.write( "Note:: The instructions are not realistic.
\n" ); document.write( "The number of nickels must be a whole number.
