Question 930165: There are 80 coins in a jar consisting of dimes (d) and nickels (n). The total value of the coins is $6.20. How many of each type of coin are there in the jars? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = number of nickels
y = number of dimes
---
x + y = 80
5x + 10y = 620
---
put the system of linear equations into standard form
---
x + y = 80
5x + 10y = 620
---
copy and paste the above standard form linear equations in to this solver:
