Sharon has some one-dollar bills and some five-dollar bills. She has 14 bills. The value is 30 dollars. Solve a system of equations using elimination to find how many of each kind of bill she has.

4 $5 bills and 10 $1 bills

Step-by-step explanation:

We know she has less than 6 5 dollars bills because 6x5=30 and that is not enough bills. So take it down to 4 $5 bills and that's 20 dollars + 10 and you have 30 dollars using 14 bills

30 = 5x + 1y
