Question 934442: A little boy has nickels and dimes in his pocket. The total value of the coins is 70 cents. The number of nickels is one less than three times the number of dimes. How many dimes and how many nickels are in the pocket? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = number of nickels
y = number of dimes
---
5x + 10y = 70
x = 3y - 1
---
put the system of linear equations into standard form
---
5x + 10y = 70
x - 3y = -1
---
copy and paste the above standard form linear equations in to this solver:
