You can put this solution on YOUR website!
Let x = # of $1 bill, y = # of $5 bill, z = # of $10 bill, then there're 3 functions you can get:
\n" ); document.write( "(1). x + 5y + 10z = 96
\n" ); document.write( "(2). x +1 = y + z
\n" ); document.write( "(3). x + y + z =23
\n" ); document.write( "From (1), (2), get 6y + 11z = 97 (4)
\n" ); document.write( "From (2), (3), get 2y + 2z = 24 (5)
\n" ); document.write( "From (4), (5), get y = 7, z =5, plug these into (2) get x = 11
\n" ); document.write( "
\n" ); document.write( "
\n" );
