F+O=22 OR F=22-0
\n" ); document.write( "5F+10=50
\n" ); document.write( "5(22-O)+10=50
\n" ); document.write( "110-5O+O=50
\n" ); document.write( "-4O=50-110
\n" ); document.write( "-4O=-60
\n" ); document.write( "O=-60/-4
\n" ); document.write( "O=15 NUMBER OF ONE DOLLAR BILLS
\n" ); document.write( "22-15=7 FIVE DOLLAR BILLS.
\n" ); document.write( "PROOF:
\n" ); document.write( "5*7+15*1=50
\n" ); document.write( "35+15=50
