Let x = # of $5 bills.
\n" ); document.write( "Let y = # of $20 bills.
\n" ); document.write( "The value equation is
\n" ); document.write( "5x + 20y = 290
\n" ); document.write( "The other equation is
\n" ); document.write( "x = y + 3
\n" ); document.write( "Substituting this into the first equation gives
\n" ); document.write( "5(y + 3) + 20y = 290
\n" ); document.write( "5y + 15 + 20y = 290
\n" ); document.write( "25y = 275
\n" ); document.write( "y = 11
\n" ); document.write( "x = 14
\n" ); document.write( "
\n" );
