Question 928285: The sum of 1.85 peso is composed of 5, 10, 25 centavo coins. There are twice as many 5 centavo coins as there are 10 centavo coins, and 2 more 25 centavo coins than half the number of 5 centavo coins. how many coins of each kind are there? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! x = 5c coins
y = 10c coins
z = 25c coins
---
5x + 10y + 25z = 185
x = 2y
z = 2 + x/2
---
put the system of linear equations into standard form
---
5x + 10y + 25z = 185
x - 2y = 0
0.5x - z = -2
---
copy and paste the above standard form linear equations in to this solver:

solution:
x = 5c coins = 6
y = 10c coins = 3
z = 25c coins = 5
