You can put this solution on YOUR website!
x=dimes, x+7=nickels, 40-(2x+7)=quarters\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "10x+5(x+7)+25(33-2x)=405 ... 10x+5x+35+825-50x=405\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "455=35x ... 13=x ... 20=x+7 ... 7=40-(2x+7)
\n" ); document.write( "
