daniel has twice as much money in onedollar bills as he does in fivedollar bills. he has 33 bills in all (all onedollar and fivedollar bills). how much money does he have?

Let
F=number of five dollar bills,
then
number of onedollar bills = (5*F)*2
Total number of bills
33 = (5*F)*2 + F
Can you complete the solution? 
no i still need your help, please

Let F=number of 5 dollar bills.
"daniel has twice as much money in onedollar bills as he does in fivedollar bills."
means that if he had 1 5dollar bill, he has 10 dollars worth of $1bills. That makes 11 bills.
If he had 2 $5bills, he would have $20 worth of 1 dollar bills. That makes 22 bills.
Can you continue? 
no i am still a little confused

Let F=number of 5 dollar bills.
"daniel has twice as much money in onedollar bills as he does in fivedollar bills."
means that if he had 1 5dollar bill (worth $5), he has twice that amount in $1bills, i.e. 10 dollars worth of $1bills. That makes a total of 11 bills, 1 five, and 10 ones.
If he had 2 $5bills (2*5=$10), he would have $20 worth of 1 dollar bills. That makes 22 bills (2 fives, and 20 ones).
If he had 3 $5bills (3*5=$15), he would have $30 worth of 1 dollar bills. That makes ______ bills? (3 fives and 30 ones).
