You can put this solution on YOUR website!
Let $\"+d+\"$ = number of dimes
\n" ); document.write( "Let $\"+q+\"$ = number of quarters
\n" ); document.write( "---------------------------
\n" ); document.write( "(1) $\"+d+%2B+q+=+17+\"$
\n" ); document.write( "(2) $\"+10d+%2B+25q+=+335+\"$ ( in cents )
\n" ); document.write( "----------------------
\n" ); document.write( "Multiply both sides of (1) by $\"+10+\"$
\n" ); document.write( "and subtract (1) from (2)
\n" ); document.write( "(2) $\"+10d+%2B+25q+=+335+\"$
\n" ); document.write( "(1) $\"+-10d+-+10q+=+-170+\"$
\n" ); document.write( "-------------------------
\n" ); document.write( " $\"+15q+=+165+\"$
\n" ); document.write( " $\"+q+=+11+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+d+%2B+q+=+17+\"$
\n" ); document.write( "(1) $\"+d+%2B+11+=+17+\"$
\n" ); document.write( "(1) $\"+d+=+6+\"$
\n" ); document.write( "----------------
\n" ); document.write( "There are 6 dimes and 11 quarters
\n" ); document.write( "----------------
\n" ); document.write( "check:
\n" ); document.write( "(2) $\"+10d+%2B+25q+=+335+\"$
\n" ); document.write( "(2) $\"+10%2A6+%2B+25%2A11+=+335+\"$
\n" ); document.write( "(2) $\"+60+%2B+275+=+335+\"$
\n" ); document.write( "(2) $\"+335+=+335+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
