For this case, the first thing we must do is define variables:
x: number of nickels
y: number of dimes
z: number of quarters
We now write the system of equations:

0.05x + 0.10y + 0.25z = 6 x + y + z = 52 y = 2x
Solving the system of equations we have:

x = 14 y = 28 z = 10
Answer:
14 nickels
28 dimes
10 quarters
