Sharon has some one-dollar bills and some five-dollar bills. she has 14 bills. the value of the bills is $30. solve a system of equations using elimination to find out how many of each kind of bill she has.

10 one-dollar  and 4 five-dollar bills.

Step-by-step explanation:

Let x = the number of one-dollar bills and y = number of five-dollar bills.

Then:

x + y = 14

x + 5y = 30      (using the values of the bills)

Subtracting the 2 equations:-

-4y = -16

y = 4

so x + 4 = 14

x = 10.

There are 10  one-dollar bills and 4  five-dollar bills.
