Let $\"+x+\"$ = number of $1 bills
\n" ); document.write( " $\"+53+-+x+\"$ = number of $10 bills
\n" ); document.write( "---------------------------------------
\n" ); document.write( " $\"+x+%2B+10%2A%28+53+-+x+%29+=+206+\"$
\n" ); document.write( " $\"+x+%2B+530+-+10x+=+206+\"$
\n" ); document.write( " $\"+9x+=+324+\"$
\n" ); document.write( " $\"+x+=+36+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+53+-+x+=+53+-+36+\"$
\n" ); document.write( " $\"+53+-+x+=+17+\"$
\n" ); document.write( "----------------------------------
\n" ); document.write( "He has 36 $1 bills and 17 $10 bills
\n" ); document.write( "----------------------------------
\n" ); document.write( "check:
\n" ); document.write( " $\"+x+%2B+10%2A%28+53+-+x+%29+=+206+\"$
\n" ); document.write( " $\"+36+%2B+10%2A17+=+206+\"$
\n" ); document.write( " $\"+36+%2B+170+=+206+\"$
\n" ); document.write( " $\"+206+=+206+\"$
\n" ); document.write( "OK \n" ); document.write( "
