Let
\n" ); document.write( "Quarters=x
\n" ); document.write( "Nickels=32-x
\n" ); document.write( "Value of a Quarter = $0.25
\n" ); document.write( "Value of a Nickle = $0.05
\n" ); document.write( "Total value of all coins = $3.6\r
\n" ); document.write( "\n" ); document.write( "(Value of a Quarter)(Quarters)+(Value of a Nickel)(Nickels)= Total value of all coins
\n" ); document.write( "0.25x+0.05(32-x)=3.6
\n" ); document.write( "0.25x+0.05(32-x)=3.6
\n" ); document.write( "0.25x+1.6-0.05x=3.6
\n" ); document.write( "0.25x-0.05x=3.6-1.6
\n" ); document.write( "0.2x=3.6-1.6
\n" ); document.write( "0.2x=2
\n" ); document.write( "0.2x/0.2=2/0.2
\n" ); document.write( "x=10\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Quarters=x=10
\n" ); document.write( "Nickels=32-x=32-10=22\r
\n" ); document.write( "

\n" ); document.write( "=========
\n" ); document.write( "0.25(10)+0.05(22)=3.6
\n" ); document.write( "2.5+1.1=3.6
