Question 516942: A collection of 105 coins consists of 1.00 and 5.00. If the total value is 205.00, Find the number of coins of each denomination in the collection

Total Number 1:00 coins = x
Total Number of 5.00 coins=105-x
x*1+5(105-x)=205
x+525-5x=205
4x=205-525
4x=320
4x/4=320/4
x=80
Total Number 1:00 coins = x = 80
Total Number of 5.00 coins=105-x = 105-80=25
