Question 935549: James collects money in his pencil box and empties it every two weeks. This time there are only Dimes and Nickels. James has twice as many dimes as he has nickels and the sum of the dimes is $1.65 more than the nickels. How many dimes and nickels does James have? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = number of nickels
y = number of dimes
---
y = 2x
10y = 5x + 165
---
put the system of linear equations into standard form
---
2x - y = 0
5x - 10y = -165
---
copy and paste the above standard form linear equations in to this solver:
