You can put this solution on YOUR website!
Let m be the amount of standard-version downloads, and n be the number of high-quality downloads. Then:
\n" ); document.write( "m+n=890
\n" ); document.write( "2.1m+4.4n=2536
\n" ); document.write( "So:
\n" ); document.write( "2.1m+4.4n=2536
\n" ); document.write( "2.1m+2.1n=1869
\n" ); document.write( "2.3n=667
\n" ); document.write( "n=290
\n" ); document.write( "m=600
\n" ); document.write( "There were 600 standard downloads and 290 high-quality downloads of the song. ☺☺☺☺
\n" ); document.write( "
\n" );
