let the no. of dimes be x
\n" ); document.write( "and no. of quarters be y\r
\n" ); document.write( "\n" ); document.write( "There were only 93 coins in the jar\r
\n" ); document.write( "\n" ); document.write( "so x+y=93 ----- eq. 1 \r
\n" ); document.write( "\n" ); document.write( "also one dime = 10 cents
\n" ); document.write( "and one quarter = 25 cents\r
\n" ); document.write( "\n" ); document.write( "so 10x+25y=1095\r
\n" ); document.write( "\n" ); document.write( " 10x+10y=930 (from equation 1)\r
\n" ); document.write( "\n" ); document.write( " => 15y=165 (subtracting one eq. from another)\r
\n" ); document.write( "\n" ); document.write( " => y=11\r
\n" ); document.write( "\n" ); document.write( "and x=82\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "so no. of dimes in the jar=82
\n" ); document.write( "
\n" );
