\"Fuwa has $125 in $5 bills and $10 bills\" ___ 5f + 10t = 125\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"If he has four more $5 bills than $10 bills\" ___ f = t + 4\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "substituting the equivalent value of f from the 2nd equation into the 1st equation ___ 5(t + 4) + 10t = 125\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for t, then substitute back to find f
\n" ); document.write( "
\n" );
