F+T=19 F=19-T
\n" ); document.write( "5F+10T=125 NOW SUBSTITUTE (19-T) FOR F IN THIS EQUATION & SOLVE FOR T
\n" ); document.write( "5(19-T)+10T=125
\n" ); document.write( "95-5T+10T=125
\n" ); document.write( "5T=125-95
\n" ); document.write( "5T=30
\n" ); document.write( "T=30/5
\n" ); document.write( "T=6 NUMBER OF TEN DOLLAR BILLS.
\n" ); document.write( "F=19-6
\n" ); document.write( "F=13 NUMBER OF FIVE DOLLAR BILLS.
\n" ); document.write( "PROOF
\n" ); document.write( "5*13+10*6=125
