You can put this solution on YOUR website!
n nickesl and q quarters
\n" ); document.write( "\"n%2Bq=20\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "$2.20
\n" ); document.write( "\"5n%2B25q=220\"
\n" ); document.write( "multiply left and right by \"1%2F5\".
\n" ); document.write( "\"n%2B5q=44\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If a system is wanted then it is \"system%28n%2Bq=20%2Cn%2B5q=44%29\".\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If you want to solve the system, ... your choice of method or, you might do some steps in your head:
\n" ); document.write( "\"q=6\" and \"n=14\";
\n" ); document.write( "you can try to recheck.
\n" ); document.write( "
\n" );
