Assuming Mary has only nickels and dimes,then:
\n" ); document.write( "nickels=x
\n" ); document.write( "dimes=x+11
\n" ); document.write( "5x+10(x+11)=215
\n" ); document.write( "15x+110=215
\n" ); document.write( "15x=105
\n" ); document.write( "x=7
\n" ); document.write( "x+11=18
\n" ); document.write( "Mary has 7 nickels, and 18 dimes..
\n" ); document.write( "
\n" );
