Let $\"+a+\"$ = the number of $50 bills you have
\n" ); document.write( "Let $\"+b+\"$ = the number of $100 bills you have
\n" ); document.write( "-------------------
\n" ); document.write( "(1) $\"+a+%2B+b+=+73+\"$
\n" ); document.write( "(2) $\"+50a+%2B+100b+=+5000+\"$
\n" ); document.write( "---------------------------
\n" ); document.write( "Multiply both sides of (1) by $\"+50+\"$
\n" ); document.write( "and subtract (1) from (2)
\n" ); document.write( "(2) $\"+50a+%2B+100b+=+5000+\"$
\n" ); document.write( "(1) $\"+-50a+-+50b+=+-3650+\"$
\n" ); document.write( "---------------------------
\n" ); document.write( " $\"+50b+=+1350+\"$
\n" ); document.write( " $\"+b+=+27+\"$
\n" ); document.write( "and
\n" ); document.write( "(1) $\"+a+%2B+b+=+73+\"$
\n" ); document.write( "(1) $\"+a+=+73+-+27+\"$
\n" ); document.write( "(1) $\"+a+=+46+\"$
\n" ); document.write( "There are 46 $50 bills and 73 $100 bills
\n" ); document.write( "-----------------
\n" ); document.write( "check:
\n" ); document.write( "(2) $\"+50a+%2B+100b+=+5000+\"$
\n" ); document.write( "(2) $\"+2300+%2B+2700+=+5000+\"$
\n" ); document.write( "(2) $\"+5000+=+5000+\"$
\n" ); document.write( "OK \n" ); document.write( "
